Parenting a toddler is a season of rapid change. One day your child is taking first steps, the next they are testing limits with a firm “no.” Having a small set of trusted, science-backed resources can help you understand what to expect and how to respond with warmth and consistency. This guide walks you through the key sources that pediatricians and child development organizations offer, all free and available online, so you can find clear answers without the noise.
CDC’s developmental milestones and the “Learn the Signs. Act Early.” program
The Centers for Disease Control and Prevention (CDC) provides a set of developmental milestone checklists from 2 months through 5 years. According to the CDC, skills such as taking a first step, smiling for the first time, and waving “bye bye” are called developmental milestones, and children reach them in how they play, learn, speak, act, and move. The checklists are available online and can be printed or completed digitally. The CDC also offers a free Milestone Tracker app that lets you follow your child’s progress and share summaries with the pediatrician.
If you ever have a concern, the CDC’s message is clear: act early. The agency advises talking with your child’s doctor, sharing your concerns, and asking about developmental screening. The American Academy of Pediatrics recommends general developmental screening at 9, 18, and 30 months and autism screening at 18 and 24 months, or whenever a parent or provider has a concern. If you or the doctor remain concerned, the CDC suggests asking for a referral to a specialist and calling your state or territory’s early intervention program to find out if your child can get services. You can learn more about early intervention and find contact information at cdc.gov/FindEI. These resources are not a substitute for standardized, validated developmental screening tools, but they give you a starting point for conversations with professionals.

CDC’s Essentials for Parenting Toddlers: routines, rules, and consistency
The CDC’s Essentials for Parenting Toddlers and Preschoolers pages offer practical strategies for building structure at home. The agency explains that routines and rules help kids feel safe and know what to expect. Three principles anchor the approach: consistency, predictability, and follow-through. Consistency means responding to your child’s behavior the same way every time. Predictability means your child knows what will happen and how you will respond. Following through means doing what you say you will do, whether the behavior is something you want to see more of or something you want to discourage.
The CDC recommends keeping routines simple and fun, and tailoring tasks to your toddler’s skill level. A familiar example is the “brush, book, bed” nighttime sequence. When a routine needs to change, the agency advises communicating the change when both you and your child are calm, explaining the reason, and letting your child know if the change is temporary or permanent. The page also includes sample daily schedules that show how some families structure mornings, afternoons, and evenings. You can find more ideas for predictable daily rhythms in our Daily Routines hub.
CDC positive parenting tips for toddlers 2 to 3 years old
The CDC’s positive parenting tips for toddlers highlight simple, everyday actions that support development. The agency notes that at this stage toddlers should be able to follow simple instructions, sort objects by shape and color, imitate the actions of adults and playmates, and express a wide range of emotions. To encourage growth, the CDC suggests setting up a special time to read books, encouraging pretend play, helping your child explore things on a walk or wagon ride, teaching simple songs, and giving attention and praise when your child follows instructions. The guidance also recommends limiting attention for defiant behavior and teaching acceptable ways to show that they are upset.
On the safety side, the CDC reminds parents to check toys often for loose or broken parts, encourage sitting while eating and chewing thoroughly, and never hold hot drinks while a child is on your lap. The agency states that drowning is a leading cause of death for children and advises never leaving a toddler near or around water without someone watching. For healthy bodies, the CDC recommends encouraging free play, making sure your child gets the recommended amount of sleep each night (11 to 14 hours per 24 hours, including naps, for toddlers 2 to 3 years old), and setting limits for screen time to no more than 1 hour per day of quality programming. The page also links to resources on nutrition, vaccination schedules, and injury prevention. For more on helping your child manage big feelings, see our Behavior and Boundaries collection.
HealthyChildren.org from the American Academy of Pediatrics
HealthyChildren.org, the parent-facing site of the American Academy of Pediatrics (AAP), offers detailed articles on discipline, tantrums, play, sleep, and feeding. One key article, “What’s the Best Way to Discipline My Child?”, outlines ten healthy discipline strategies. According to the AAP, these include showing and telling children right from wrong with calm words and actions, setting clear and consistent rules, giving consequences and following through immediately, listening to your child’s side of the story, and catching them being good with specific praise. The AAP also explains that ignoring bad behavior can be effective when the child is not doing something dangerous, because it teaches natural consequences.
The article describes time-out as a tool that works best when you warn the child, remind them what they did wrong in few words and with little emotion, and remove them from the situation for a pre-set length of time. The AAP suggests a rule of thumb of 1 minute per year of age. For children at least 3 years old, you can try letting them lead their own time-out by saying, “Go to time out and come back when you feel ready and in control.” The AAP policy statement emphasizes that spanking, slapping, and other forms of physical punishment do not work well to correct behavior, and that harsh verbal discipline can lead to more behavior problems and symptoms of depression. Instead, the AAP advises modeling the behaviors you want to see and staying consistent. For a deeper dive into positive approaches, read our article on Toddler Tantrums and Positive Discipline.
ZERO TO THREE: setting boundaries with warmth
ZERO TO THREE, an organization focused on the earliest years, explains that babies and toddlers have big feelings they cannot always control, and setting boundaries helps them feel safe. The organization notes that children test limits because they want to know that the limit is solid, much like a child walking along a fence and testing every part to see if they can break through. When the fence is strong and reliable, limit-testing decreases over time.
ZERO TO THREE offers several prevention strategies. Decide if a limit is truly necessary and where you can be flexible. Be consistent: if your child throws a toy, put it away every time, right away. Offer tools to help them wait, such as a kitchen timer or a puzzle. Help with daily transitions by giving a heads-up five minutes before a change, then two minutes, then one minute. Offer choices that give a sense of control, like “Do you want the blue or red cup?” but avoid asking questions when no choice is offered. The organization also stresses the importance of staying calm and present during a tantrum. Co-regulation strategies, such as using a quiet, steady voice and a kind tone, can help both of you calm down. If you are too angry, take a short break yourself after making sure your child is safe. ZERO TO THREE reminds parents that all toddlers push limits, and this new independence is an important part of development.

CPSC: toy recalls and button battery safety
The U.S. Consumer Product Safety Commission (CPSC) is the federal agency that issues recalls and safety warnings for consumer products, including toys and household items. The CPSC warns that button cell or coin batteries are associated with thousands of emergency department visits every year, and a swallowed battery can burn through a child’s throat or esophagus in as little as two hours. The agency advises keeping remotes, electronics, and products with accessible button batteries away from children if the battery compartments do not have a screw closure to secure them. Toys with button cell or coin batteries are required to have a secure closure requiring a screwdriver, coin, or tool to open, so check the toys in your home to make sure compartments are secured. The CPSC also says to immediately place non-conductive tape over the terminals of a discharged battery and discard it at a battery-collection center.
If a button cell or coin battery is swallowed, the CPSC directs caregivers to seek medical attention immediately. The National Capital Poison Center recommends giving honey to children 12 months and older on the way to the emergency room to reduce injury, but only if the ingestion occurred within the past 12 hours, and to give 10 mL of honey every 10 minutes for no more than six doses. Do not delay going to the emergency room to obtain or give honey. The CPSC also provides the National Battery Ingestion Hotline (800-498-8666) and the Poison Help Line (800-222-1222) for treatment information. You can stay current on recalls through the CPSC website. Our Choosing Toys, Books and Parenting Resources for Toddlers article covers how to use recall information when selecting playthings.
How to use these sources alongside your pediatrician
These resources are most powerful when you pair them with regular well-child visits. The CDC’s milestone checklists can help you notice patterns and bring specific questions to the doctor. The AAP’s discipline guidance gives you a shared language to discuss behavior challenges. ZERO TO THREE’s boundary-setting ideas can be adapted to your family’s values. And the CPSC’s recall and safety information helps you keep the home environment safer. None of these sources replace individualized medical or developmental advice. If you have a concern, the CDC’s instruction to talk with your child’s doctor and, if needed, contact your state’s early intervention program is the most important step you can take.

Frequently asked questions
Do I need to use all of these sources?
No. Many parents find it helpful to start with the CDC’s milestone checklists and the AAP’s discipline article, then explore ZERO TO THREE or the CPSC as specific needs arise. The key is to choose sources that are updated by recognized health and safety organizations and to discuss any concerns with your child’s pediatrician.
What if my toddler is not meeting a milestone on the CDC checklist?
The CDC advises that you act early. Talk with your child’s doctor, share your observations, and ask about developmental screening. If you or the doctor remain concerned, ask for a referral to a specialist and call your state’s early intervention program to learn about available services. The CDC’s “Learn the Signs. Act Early.” page and the Milestone Tracker app can help you prepare for that conversation.
How do I know if a toy is safe for my toddler?
The CPSC recommends checking that battery compartments on toys with button cell or coin batteries are secured with a screw closure. Regularly inspect toys for loose or broken parts, and stay informed about recalls by visiting the CPSC website. The CDC also suggests checking toys often for damage and encouraging your toddler not to put pencils or crayons in their mouth.
