Getting toddler to sleep with newborn in the house is one of the hardest adjustments a family can face. A toddler who once settled easily may suddenly resist bedtime, wake at night, or climb out of the crib, just as a newborn’s feeding and waking schedule takes over the household. This guide compares five sleep books that address children across the early years, so you can choose the one whose approach matches your family’s values and daily routine. We selected these titles based on the specificity of their advice, the credentials of their authors, how clearly they explain the reasoning behind their methods, and the patterns parents commonly describe in reader feedback. We have not tested these methods ourselves, and we are not medical professionals, so treat the guidance here as a starting point rather than a prescription.

Buying Guide
Match the Method to Your Family’s Values
Sleep books differ mainly in how they handle crying, comfort, and parental presence at bedtime. Before buying, decide which approaches you are willing to try. A book that feels too strict can lead to abandoning the plan after a few nights, while one that is too permissive may not solve the problem. Read the table of contents and the introduction to see whether the philosophy fits your household.

Age Range Covered
Some books focus on newborns, others on toddlers or school-age children. Because you are managing a toddler and a newborn, look for a title that addresses both, or at least explains how a baby’s routine can affect an older sibling. A book with a wide age range can be useful for planning ahead as the younger child grows.
Good picks for this: It’s Never Too Late to Sleep Train; Sleeping Through the Night, Revised Edition
Depth of Explanation
Some parents want a short action plan, while others want to understand why sleep changes at different ages. If you are someone who needs the reasoning before trying a technique, prioritize books that explain sleep development. If you need quick answers during a difficult night, choose a title with clear, numbered steps.

Troubleshooting Coverage
Toddler sleep problems often involve bedtime resistance, night waking, early rising, and difficulty staying in bed. Check whether the book addresses the specific problem you are facing. Look for sections on common situations such as transitions, illness, and changes in routine, since a new baby often triggers several of these at once.
Good picks for this: Sleeping Through the Night, Revised Edition; The No-Cry Sleep Solution, Second Edition
Length and Readability
Sleep-deprived parents may have little time to read. A shorter, well-organized guide is easier to use than a dense volume, while a longer reference can be valuable if you want to read once and refer back later. Consider how much time you realistically have each week before choosing.

Currency of Information
Recommendations about sleep have changed over the years, particularly around safe sleep for infants. Check the publication or revision date and confirm that any advice about safe sleep environments matches current guidance from pediatric and government sources. When in doubt, follow your pediatrician’s recommendations over any book.

Fit With Your Pediatrician’s Advice
Some sleep problems have medical causes, including sleep-disordered breathing, reflux, or illness. A good book will say when to seek medical help. If your toddler snores loudly, pauses in breathing, or seems unusually tired during the day, consult your pediatrician before trying behavioral changes.

FAQ
How do I start getting my toddler to sleep when the newborn wakes often?
Begin by keeping the toddler’s bedtime routine the same each night, even when the newborn is fussy. Use a short sequence such as a bath, pajamas, two books, and a song. Assign one parent to the toddler’s bedtime if possible, so the baby’s feeding does not interrupt the older child’s settling.
Should I let my toddler cry at bedtime while the baby sleeps?
That is a personal decision. Crying-based methods are controversial, and some families prefer gentler approaches. If you choose any method, make sure your toddler is safe, that you are responding to illness or distress, and that the plan is consistent. Talk to your pediatrician if you have concerns about your child’s emotional wellbeing.
Why does my toddler’s sleep get worse after a new baby arrives?
Changes in routine, a new sibling, and a parent’s divided attention are common reasons. Toddlers often respond to these transitions by resisting bedtime or waking more. Keeping familiar rituals and giving the toddler some one-on-one time during the day can help them feel secure.
Can I have my toddler sleep in the same room as the newborn?
Current safe sleep guidance from the American Academy of Pediatrics recommends that infants sleep alone, on their backs, on a firm surface, in the same room as parents, for at least the first six months. Toddlers can often share a room with a baby if the room is safe, but the infant’s sleep space must meet safe sleep standards. Check the Consumer Product Safety Commission for guidance on safe sleep products.
How long does it take to see improvement in toddler sleep?
Many families notice some change within one to two weeks of consistent routines, though full adjustment can take longer, especially after a major change. Progress often comes in steps, with some nights better than others. If sleep problems persist for several weeks or affect your child’s daytime behavior, speak with your pediatrician.
When should I talk to a doctor about my toddler’s sleep?
Contact your pediatrician if your toddler snores loudly, stops breathing during sleep, wakes with night terrors frequently, seems very sleepy during the day, or has sleep problems alongside other symptoms. Sleep-disordered breathing and other medical causes need professional evaluation rather than behavioral fixes.
Do I need all five books?
No. Most parents do well with one book that matches their approach. Start with the title whose philosophy best fits your family, and add a second only if you need a different perspective on a specific problem.

Getting toddler to sleep with newborn is a common challenge, and the right book can give you a clear plan.
