Babies are generally too big for a bassinet once they are four months old and above.

At this age, their weight will be more than what most bassinets can support.

However, every baby grows uniquely.

You can determine when your little one needs to get off a bassinet to another bed by paying attention to some cues. 

You will find these details and tips for getting your baby set for a crib as you read on.

How to Know When Baby is Too Big for Bassinet?

When is the baby too big for a bassinet?

Are you wondering if it is time to stop your baby from sleeping in a bassinet?

Here are some things to consider before making that decision.

Bassinet Weight Limit

You should know the recommended weight limit of your bassinet at the time of purchase.

Most bassinet weight limit ranges between 15 lbs and 33 lbs.

You should stop putting your baby in a bassinet once your baby has outgrown your bassinet weight limit.

In fact, we will advise you not to wait till your baby weighs exactly the recommended weight of the bassinet.

That could compromise your newborn's safety.

Your Baby's Age

Like weight, growth is connected with a baby's age.

Hence, age is an essential pointer to your child's need for a new bed.

According to pediatricians, the average weight of babies at four months is 40lbs.

Also, the average baby length at four months is 25in (63.9 cm).

Consequently, your little one may already exceed the bassinet's weight limit or have little legroom.

So you should consider getting your baby ready for a bigger sleeping space at 4months.

Baby's Activity Level

Do not forget that bassinets are essentially for newborns.

Hence, if you notice that your baby has become super active before the recommended age, move your little champ out of the bassinet.

Bassinets do not have the protection that cots afford for more active babies.

The side guides are low and soft. You don't want your baby to roll out from it.

What to do When Baby is Too Big for Bassinet?

Perhaps you've noticed that your baby has outgrown a bassinet, and you are wondering what to do to retain the kind of atmosphere a bassinet offers.

There are many things to do, but the most common one is by transitioning baby to crib.

A crib, unlike a bassinet, can accommodate a heavyweight (more than 40 pounds).

But because there is going to be a change in environment, babies may feel unsafe and uncomfortable if you suddenly move your baby from bassinet to crib.

That's why it is pertinent for you to know how to prepare your baby for this transition.

So, how can you achieve a safe transition?

Transitioning Baby from Bassinet to Crib

Now that you know when to transition baby to crib, here are the tips for transitioning baby from a bassinet to a crib:

  • Remove movement restrictions: You can begin by leaving the swaddle out of the bassinet to let the baby feel less surrounded. It may take some time for your baby to adjust to sleeping without a swaddle, but the champ will be fine.
  • Familiarize baby with crib: With time, try letting babies sleep or play in the crib in the afternoons till they fully adapt to their new environment. The crib should be in the same room as the bassinet. Do not forget to leave out toys or any accessories from the crib.
  • Use bassinet bedding in the crib: Babies usually have a fine sense of smell at birth. They can differentiate between familiar and strange settings through smell. Using the same bedding in their bassinet for a crib can be reassuring to babes.

Meanwhile, since transitioning is in stages and not abrupt, we advise you to begin the transition before your baby outgrows the bassinet so you won't have to rush the process.

Benefits of Bassinet

Bassinets are not as strong and durable as cribs.

But there are several reasons why this infant bed is the first choice for mothers to put in their sleepy babes.

Here are four of them:

  • Portability: Bassinets are easy to move around since they are lightweight and foldable. These qualities allow you to have your baby beside you anywhere in the house. Most bassinets with stands have wheels for increased mobility. Besides, you can always take it on a journey, so your baby has a nest regardless of location.
  • Economical: Bassinets are relatively low-cost compared to other types of baby beds. People find them as a budget-friendly option without compromising comfort for babies. Bassinet cost falls between $60 to $400, depending on the material type and added perks.
  • Offers Protection: When choosing a baby's bed, safety is always considered, and bassinets tick the box. Most products have a flytrap that you can zip up to keep your baby safe from insects. Some brands also have a hood to prevent sunrays from disturbing your baby's sleep.
  • Storage option: You would have noticed some bassinets with built-in pockets at the side or underneath for raised models. These pockets allow you to keep some baby's essentials like cloth, diapers, etc.


A bassinet is a safe place to put a baby.

But stop putting your baby in a bassinet once the baby weighs more than 33 lbs or when the baby is four-month-old.

Once your baby has outgrown a bassinet, consider moving the baby to another bed, such as a crib that can accommodate the heavyweight.

However, before you move your baby from a bassinet to a crib, ensure there is a proper transition.

Otherwise, your baby may not give you the comfort you deserve while sleeping in a crib.

Lastly, provide adequate supervision of your baby during and after transitioning from bassinet to crib.
