Should Babies Sleep in a Crib?

If you're preparing for your little one’s arrival, one of the first questions you might have is, “Can a newborn sleep in a crib?” The short answer is yes—a crib is a safe sleep environment for a newborn baby from day one, provided it meets current safety standards. While it's common for parents to wonder if newborns do sleep in cribs right away or if a bassinet would be better, ultimately, both are safe options, and the choice depends on what works best for your family.

When to Start Using a Crib

Your baby’s crib is an essential item, but when should they start sleeping in itMany parents begin using a crib from day one, while others opt for a bassinet during the early weeks. 

Bassinets are smaller, more portable, and often easier to place beside your bed, making nighttime feedings more convenient. Cribs, on the other hand, offer more space and long-term use, and they’re a great choice if you want to establish a consistent sleep space from the start.. Getting your baby to sleep in a bassinet follows similar principles to getting your newborn to sleep in a crib, so it’s fine to start wherever you feel most comfortable.

Can a newborn sleep in a crib? Absolutely. It’s both safe and common for newborns to sleep in a crib from day one—as long as it meets current safety standards and includes a firm mattress and snug-fitting sheet with no soft bedding or extras.

Whether you begin with a bassinet or go straight to a crib, the most important thing is choosing a safe, consistent setup that works for your family.

When to Stop Using a Crib

Along with asking when to start using a crib, parents also wonder how long babies sleep in cribs. There’s no standard age for outgrowing a crib and switching to a bed, as all children grow at different rates. Consider the following to determine when to stop using a crib for your child:

• By the time your child is about three feet tall, they should no longer sleep in a crib, according to experts.

• Check the manufacturer's guidelines when you buy your crib, as there may be a maximum height, weight, or age limit.

• To ensure the crib is safe during both babyhood and toddlerhood, you’ll need to lower the mattress height from time to time. This will prohibit your toddler from climbing out or falling over the rails.

Before your child can climb out—even with the mattress at its lowest level—it’s best to transition to a toddler bed. Many modern cribs convert into toddler or full-size beds, making the change a little easier for both you and your little one.

Possible Reasons Why a Baby Won’t Sleep in Their Crib

When you put your little one down for a nap or bedtime, cries and protests may feel frustrating—but they don’t always mean your baby won’t sleep in a crib. More often, they’re expressing a natural reaction to separation. Babies thrive on closeness, and being apart from you, even briefly, may feel unsettling for them, especially in the early months. In many cases, your infant doesn't want to sleep in a crib because they’ve grown used to falling asleep in your arms or in a different environment, like a swing or stroller. This association could make the transition to the crib a bit more challenging.

Sleep regressions are another common cause. As babies grow and reach new developmental stages, their sleep patterns may temporarily shift, leading to more fussing or frequent wakeups in the crib.

If your baby refuses to sleep in a crib, know that a little crying before falling asleep is normal. Many babies settle after a few minutes. Gentle sleep training methods may also help, gradually encouraging your baby to self-soothe and fall asleep independently, with plenty of reassurance along the way.

If the crying feels excessive or something seems off, consult your baby’s healthcare provider to rule out any underlying concerns.

Helping a Baby Sleep in Their Crib

When getting your baby to sleep in a crib, timing can make a big difference. Experts recommend placing your baby in the crib at the first signs of drowsiness—not after they’ve fallen asleep. This helps your baby associate the crib with falling asleep, not just waking up in it. 

Sometimes, your baby won’t sleep in a crib (or anywhere) because they need something. Check whether your little one needs feeding or a diaper change, or whether they may be feeling sick or have a fever.
