Many families assume sleep training has to happen “one child at a time,” but when you have a baby, toddler, or preschooler all struggling with sleep, waiting it out often makes nights harder. The sleep deprivation goes wild, and the “domino effect” of one child waking another becomes a nightly reality.
The good news? You CAN sleep train multiple kids at different ages at the same time. It requires a solid strategy and realistic expectations, but with the right approach, you can restore peace to your entire household at once.
Is It Possible to Sleep Train Multiple Kids at Once?
The short answer. Yes! However, it’s not about using a one-size-fits-all approach. It’s about alignment.
While you might use different techniques for a 6-month-old versus a 3-year-old, the goal is to have them learning the same skill, independent sleep, simultaneously.
Some considerations you may want to think about before tackling sleep training multiple kids at the same time:
- If one child is currently ill
- During major transition (moving house, starting a new school)
- Right before a scheduled family vacation
Understand Each Child’s Sleep Needs First
A baby’s sleep biology is vastly different from a preschooler’s. To succeed, you must respect their differences:
Infants: Focus on wake windows and biological sleep cues. Their “sleep pressure” builds quickly.
Toddlers & Preschoolers: Focus on clock-based schedules and clear boundaries
The Golden Rule: You are following one “Household Sleep Plan,” but with different expectations for each child based on their developmental stages
If your children aren’t at the ages where their bedtimes or sleep schedules are the same or similar, try and let your older child spend some quiet time. Quiet time could entail having your child read in their room or quietly play while you do bedtime routine with your younger child. Like I mentioned above, it’s great if you can have your kids even do one or two steps or their bedtime routine together. It doesn’t always work for everyone. Even if one of your children as an earlier bedtime or they are different by 30 minutes or so, simply reading a book together can have huge positive effects for everyone.
Choose a Method that Works Across Ages
You don’t have to use the exact same method for every child, but your philosophy should be consistent.
For Babies: You might choose a more responsive approach like “The Chair Method” or “Timed Checks.”
For Old Kids: Use “Stay in Bed’ rules and rewards with clear boundaries.
Consistency is Gold: If you are firm with a toddler, but “give in” to your infant (or vice versa), the older child will sense the inconsistency, which can lead to more resistance.

Align Bedtimes (But Don’t Force a Match)
Trying to put a baby and a toddler to bed at the exact same second is a recipe for disaster and meltdowns. I would recommend aiming for staggered bedtimes.
Putting the younger child down first, then using that one-on-one time to finish the older child’s routine. Staggered bedtime can also be a super effective method for vacation or travel, or when children are room sharing. This is a great time to crank the white noise. It will be your best friend for preventing your crying baby from waking a light-sleeping toddler.
Creating One Predictable Evening Routine
Chaos thrives in the unknown. Having a share family routine can really anchor your evenings.
Sample Bedtime Schedule:
6:30 PM: Group bath time or “pajama party” in the living room.
6:45 PM: Family snack or final milk feeds
7:00 PM: Baby’s final white noise/swaddle/lullaby (lights out for baby)
7:15 PM: Individual reading time and quality time with the older child
7:30 PM: Final tuck-in for the older child
Handle Night Wakings Without Undoing Progress
This is the part parents dread the most. It honestly can bring a lot of anxiety. The anxiety of the unknown.
If both are crying, take a deep breath. It will feel like an emergency, but it’s okay to attend to one child for a few minutes while the other waits. Lean heavily on the plan. Stay calm and try to prevent “frantic energy” that your child can feed off of.
The first few nights can be messy. Expect protesting and perhaps some chaotic progress. Your toddler may improve quickly because they understand the rules. Your baby might take a few extra nights to find their “thumb” or self-soothing rhythm. Don’t be surprised if nights 3 or 4 are harder than night 1. This is really normal and a common final pushback before new habits will stick.
If we can help our children learn and implement the basics of independent sleep at a young age, it can have huge lifelong benefits in regards to their sleep. Getting into a solid routine once you have more than one child has major benefits to you, as the parent. This, in turn, will have positive impacts on the whole family.
Sleep training multiple kids isn’t about perfection – it’s about structure. It’s about teaching your children that sleep is a gift and that the “rules” of the house apply to everyone. With a clear plan, you aren’t just training your kids; you’re reclaiming your evenings and your sanity.

“Working with Rachel the last few weeks has been a great experience! She is a mother of two toddlers herself, so she really understands the different sleep challenges that can occur from the newborn stage on. She helped me with my 2 and 3 year olds sleep schedules in order to combat early morning wakings. And gave me practical tips on how to avoid crib climbing and boundary pushing. She is knowledgeable, dedicated and passionate about helping families. I highly recommend Rachel to anyone who needs support!”
