Before buying a Pack N Play for a newborn, every parent should need to know; how long can baby sleep in pack n play & when it is the best time to stop using it.

As you know, Pack N Play provides a controlled sleeping environment that gives the baby & the parents a sense of security & lowers the risk of SIDS.

That’s why [1] & American Academy of Pediatrics (APP) [2] it.

It is not only used for sleeping purposes; you can use it for a diaper changer, a short nap, playtime, etc.

How Long Can Babies Sleep In Pack n Play

But the question is; how long can a baby sleep in a pack and play, and when to stop using it? And also, when to stop using pack n play bassinet? If it comes with it, and when to lower pack n play mattress?

All these questions look pretty straightforward, but answering them is a little complicated.

To understand this, you first need to understand three main factors; AGE, WEIGHT, AND HEIGHT, which define how long you can use it.

So, let’s check this.

How Long Can Baby Sleep In Pack N Play?

Your baby can sleep in Pack n Play as long as they are comfortable in it, and doesn’t cross the pre-set Age limit (1.5 to 3 year) & weight limit ( 30lbs – 40 lbs ) to be on the safe side Or until the baby doesn’t gain the strength to climb on the sidewall ( up to 35 inches tall ) by himself.

Let me break down these factors more practically with daily life examples to make it easier for a parent to understand.

1.) Comfortable Size & Right Age Limit:-

Generally speaking, the baby’s size is a critical determining factor in deciding how long can a baby sleep in a pack and play.

Pack n play dimension and size

Usually, the size of a pack and play is approximately 40 x 28.5 x 29 inches (depending upon the manufacturer of the Pack n play).

Once your baby starts feeling uncomfortable or not fitting in it, then it’s time to say farewell to the Pack n Play. But, keep in mind; babies differ in their patterns of growth.

Some grow slower, and some faster than others.

So, you need to be vigilant for your baby’s safety and keep an eye on the baby’s growth.

Sleeping in a restricted space can pose a huge problem and is unsuitable for proper growth for a baby who has outgrown the Pack n Play.

So, at what age to stop using Pack and play?

The standard age range for Pack and play is 1.5 to 2.5 years approximately (depending on the pack n play dimensions ) or until the baby or toddler feels comfortable in it.

In that age range, a baby will grow enough to move out from pack-n-play.

Pack And Play Age Limit & Dimensions:-

Pack N Play Dimensions 36 x 24 x 25 inches To 40 x 29 x 31 inches, Approximately
Standard Pack And Play Size 38 x 26 x 27 inches, Approximately
Pack And Play Age Limit 1.5 – 2.5 Years, Depending Upon size

 2.) Weight Limit & Floor strength:-

Pack n plays differ in their weight limit recommendations. The pre-set weight limit for your baby to stop using the Pack n Play is approximately 30 lbs ( 14 kgs).

A baby who is over the above-recommended weight can cause the Pack n Play to collapse.

But keep one thing in mind, not all pack n plays have weight limit recommendations.

The bottom of some pack n plays touches the floor, so there is no need to worry about the weight limit in such cases.

On the other hand, if you are using a bassinet on the pack n play for sleeping, that comes with it.

Then make sure you follow the weight & age limit recommendation set for the bassinet by the manufacturer.

Note:- Only the Age and the weight limit are the primary factors that define how long a baby can sleep in pack n play bassinet.

Read this guide: When to stop using the bassinet.

Also, ensure your baby sleeps on the perfect flat surface as per the APP’s recommendation. Placing your baby on an uneven surface will increase the risk of SIDS.

Weight Limit For Pack And Play & Its Bassinet:-

Pack And Play Weight Limit Between 30 – 40 Pounds approx.
Pack And Play Bassinet Weight Limit Between 15 – 25 Pounds approx.
Pack And Play Floor Strength No Limit If The Base Touches The Floor
Pack N Play Changing Table Weight Limit Between 30 – 35lbs approx.
Pack N Play Top Level Weight Limit Between 30 – 40 Pounds approx.

3.) Sidewall Height & Strength:-

The pack n play height & the strength greatly define how long your baby can safely stay in the Pack and play.

Your newborn baby will grow faster than you think; soon, they start rolling in and moving in or climbing on the sidewall.

Most pack-n-play side walls are Mesh made for better breathability and lower temperature.

But that Mesh is not strong enough to hold the baby standing or push when climbing on it.

Suppose your baby stands near it and pushes your Pack and play wall. It can flip, which could lead to an accident [3].

The American Academy of Pediatrics found that most injuries that the babies incurred were in the neck and head regions due to falls, some due to product failures and others due to consumer negligence.

Some babies may not have crossed the recommended weight and age limit for Pack and play but are pretty tall and can easily climb on the side to move out of it.

In short, when your baby starts pushing the side or standing in pack n play, that is a clear sign that it’s time to stop using Pack and play and switch them to a crib or standard bed.

Pack N Play Height Limit:-

Pack N Play Height Limit:- 35 inches (88.9 cm)

Watch these CDC [4] safety guidelines for safe sleeping.

Always remember that “safety” should go before “comfort.”
