There are several factors that you should consider when buying a swaddle or sleep sack and one of them is age. Is your baby a newborn, 3 months, or 6 months? Picking a swaddle for a newborn (0-2 months) is not difficult because their needs are limited. They simply need a swaddle that creates a womb-like environment. However, choosing the best swaddle for 3 month old baby may be challenging because babies at this age want to explore mostly using their hands.

Nonetheless, most babies love to be swaddled especially when you choose a swaddle that meets their needs. Just like babywearing, swaddling helps babies sleep longer, soothes and calms them, minimizes the risk of SIDs, and reduces anxiety.

Some babies, particularly newborns, like to be swaddled with their hands in while older babies aged 3 months and above may prefer to have their hands out so that they can touch their face and self sooth. For this reason, you need to choose a swaddle that matches your baby’s preference and age. We understand this and that is why we have prepared this article to help you make a good choice when buying.

What to consider when buying the best swaddle for 3-month-old baby

  • Size

Swaddles come in different sizes from 0 months and above. Thus, size is an important factor to consider because it determines how cozy and comfortable your baby will be when swaddled.

If you get one that is too small, they may feel restricted or even overheat. An oversized one on the other handle causes a suffocation risk.

Therefore, get the perfect size for a 3-month-old. One that is not too small and not too big yet it should have enough room to allow for the movement of legs. At 3 months, babies like to play with their hands and legs, so they should not be restricted.

  • Fabric

The material of the swaddle is also an important factor to consider. Different brands use different materials, which also determine their quality.

As we have seen in our reviews above, most swaddles are made from cotton. This is probably because it is super soft and high quality.

  • Weather

Are you buying the sleep sack for summer or winter? You need to consider the weather and get an appropriate swaddle for that particular season.

If you are looking for the best swaddle for summer, a lightweight swaddle would be appropriate. For cold weather, get a swaddle that will keep your baby warm; probably one that is fleece-lined or quilted.

  • Ease of use

A swaddle sleep sack should be easy to use. You should be able to change the baby’s diaper while still in the sleep sack.

Thus, you need to get a swaddle blanket that has a zip that runs from top to bottom. This will help you to simply unzip it from the bottom and change the diaper without waking up the baby.

  • Price

Bearing in mind that babies outgrow swaddling at around 6 to 8 months, you need not invest too much on a sleepsack. Nonetheless, get one based on your budget and factors that we have discussed above. You may find that some swaddles are expensive and do not meet all your requirements while others are affordable and have all the requirements you need.

FAQ about the best sleep sack for 3 month old baby

Q 1. Should I swaddle my newborn at night?

Babies are swaddled right from birth. It keeps them warm and mimics the womb environment, which enables them to adjust to the outside environment gradually.

Thus, it is okay to swaddle a newborn at night in order to make them feel safe, warm and comfortable. This translates into a sound sleep for the baby and you get to relax as well.

Q2. When to stop swaddling my baby

Swaddles have replaced the traditional blankets. This means no more loose items in the cot or crib that can cover the baby’s face and cause suffocation.

It is recommended that you should stop using a swaddle the moment you notice that your baby is attempting to break out of it or wants to start rolling over. This is because once they roll on their tummy, they may be unable to roll back up since their hands are swaddled; thereby causing suffocation.

If you want to keep swaddling your baby, a sleep sack that allows them to have their arms out is more appropriate than a swaddle that covers their arms completely. For instance, with the Burt Bee’s sleep sack, babies can use their arms to sit up since they are not swaddled in.

Q 3. Should I swaddle with arms out or in?

The decision on whether to swaddle with arms out or in depends on your baby’s age and preference.

Newborns are usually swaddled with their arms in so as to prevent startle reflex. As they get older, they may want to self-sooth using their hands; hence, they may prefer being swaddled with their arms out.

Most 3 month old babies will enjoy being swaddled with arms out.

Q4. Do all babies like to be swaddled?

Most newborn babies like being swaddled because it gives them comfort and warmth similar to what they were experiencing in the womb.
