If you’ve been using a bassinet or bedside co-sleeper for your newborn, your little one may have developed a sleep association with sleeping near you. Sleep associations include the environment, routine, and objects present at the time your little one falls asleep.1 Basically your baby is learning to fall asleep under very specific conditions, making it harder for them to fall asleep with a new routine or in a different environment … like a crib!2
While you can work to change sleep associations so that your little one is able to fall asleep in a new space, know that these associations become stronger with age.1,2 For this reason, it’s best to start a transition early on if you know that your ultimate goal is to get your baby sleeping in a crib.
Developing healthy sleep habits will be key in this transition, as well as to help prevent sleep issues in the future.1
It’s common to feed or rock baby to sleep before putting them down in a bassinet or crib; however, this makes it so that your baby can only fall asleep when being rocked or fed (a sleep association!). While you can still rock and feed as part of their bedtime routine, aim to put baby down while they are drowsy but not yet asleep. This is an important part of developing healthy sleep habits.3
Self-soothing for nighttime wake-ups is also a key part of the process. Allow your baby to fuss for a few minutes to see if they can put themselves back to sleep.3 Allowing your little one to self soothe will help in the transition to the crib.

Understanding your little one’s sleep cues and responding to them promptly will help develop healthy sleep habits by following your baby’s natural sleep rhythm as it develops and changes. Put your baby to bed tired but still awake.3
Your baby’s sleep cues may include:
Little ones thrive on routine.4,5 Creating a bedtime routine that you use consistently will help your little one know bed time is coming.6 Make sure this routine includes the crib, and stick with it! Your routine may look something like: bath, brush teeth, book, song and/or rock, place in crib drowsy.
If you already have a bedtime routine, you can use that one while transitioning your little one to the crib. This helps reduce how much change is going on at one time. For example, if your baby is very young and still swaddled,7 keep baby in the swaddle as they become used to sleeping in the crib.

Homeostatic pressure, or the feeling of needing to sleep, is highest at bedtime (as opposed to daytime naps), when the body naturally consolidates its longest stretch of sleep.8 Take advantage of this and begin the process by laying your baby to sleep in the crib for bedtime rather than naps. Hopefully your little one will then get a nice stretch of sleep in the crib to facilitate a new sleep association.

Anytime you ‘ask’ your baby to make a change, remember there will be an adjustment period. Expect the transition of getting your baby to sleep in a crib to take a few nights and possibly much longer depending on your baby’s age.9
Under 4 to 6 months
If your baby is younger than 4 to 6 months, nighttime wakeups for feedings are still a normal part of their development. Helping your little one sleep in a crib at this age will be focused on responding to their physical needs (feedings, temperature, diaper, comfort) while developing good sleep habits.1
At this age focus on: understanding your infant’s cues for sleep, allowing them to self-soothe, and helping them develop day-night differentiation (sleeping more at night than during the day).14 It’s normal for babies to wake up often, fuss and wiggle for a bit, then fall back asleep.15 Let your little one fuss for a few minutes before responding to see if they’ll fall back asleep.
If your baby is well-fed, warm, and their diaper is dry, but they still aren’t able to fall asleep on their own, comfort your little one as needed. As soon as they are drowsy again, place them back in the crib to fall asleep completely.
Over 4 to 6 months
If your baby is older than 4 to 6 months when you transition to crib sleeping, it’s ok to maintain a bit more distance during your comforting sessions. As always, lay your baby down in the crib while drowsy. If baby is not able to self-soothe, offer verbal soothing or tummy rubbing until your little one is calm.1, 11 Keep the room dark and try not to pick up your baby.6 You can continue going in every 5 to 10 minutes as needed until baby falls asleep .12, 13
Regardless of age, provide more support at the start of the transition, and slowly offer less over the days or weeks it takes for your little one to initiate sleep in their crib independently. Note that babies often don’t have a regular sleep cycle until 6 months old.3

This is a tough transition for both you and your baby, so once you begin this process, stay strong and be consistent. Babies are very smart and will know when they’ve ‘won’ the battle. If you relent and go back to sleeping in the same room, it may be a more difficult transition the second time around. Know that baby is safe in the crib, is in a loving environment, and that this too shall pass.
