What to Look for When Choosing a Baby Bathing Suit

There are many options available in the stores and online for your toddler when you plan to take them for a splash in the pool or on the beach holiday. It is wise to make an informed choice before you invest in swimwear for your infant.

Skin Sensitivity: Most of toddler bathing suits are designed for the baby’s soft skin.

 If you are aware of a specific skin allergy of your baby’s skin, do read carefully, of which material the swimsuit is made of before you decide to or order online.

Style/Design: You know your baby the best. Whether s/he will be more comfortable in a onesie or a 2 piece set is a wise decision to make as per his/her energy levels and the personal choice.

Potty training: In case your baby is not potty trained, it is advisable to use a baby swim diaper (reusable or disposable) along with the baby’s swimsuit to save yourself from any leakages. Many bathing suits for infants even come with a reusable in-built swim diaper too.

Rashguard protection: If your toddler’s skin is prone to rashes it will be a good option to choose from the rash guard swimwear for your baby.

Colour and prints: Most of the infant swimwear comes in super cute designs which makes your munchkin look adorable. So, do take out that camera on your next visit to the pool or beach to make some lovely memories for you and your family to cherish. 

FAQ about Baby Swimsuits

Q1. Do babies wear diapers under swimsuits?

Babies from 0-18 months who are not potty-trained are required to wear a swim diaper as part of the swim gear. They are mandatory in pools or for swim classes. The Diapers can be disposable or reusable. Few of the baby swimsuits come with attached baby diapers to save them from leakages. 

Even if you are planning a visit to the beach, a swim diaper can be a life savior to keep everyone safe and having trouble cleaning the mess.

Q2. Do babies need to wear rash guards?

For babies, under six months it is advisable to use swimwear made of rash guard material since you can’t use sunscreen on them. The rash guard protects the baby’s skin from the harsh sun. 

For babies, over 6 months it is not necessary but advisable since it protects their sensitive skin from rashes, especially if you are planning a long day at the beach or a pool.

Q3. What UPF swimsuit to get for a baby?

UPF stands for Ultraviolet Protection Factor. To protect your baby’s skin from harmful rays UPF 50+ works well. It means that it will let 1/50th of the UV rays pass through the material. As per the Skin Cancer Foundation anything to be called “Sun protective” should be above 30 UPF and UPF 50+ provides “excellent protection” as per their guidelines.

Q4. Why are baby swimsuits long sleeves?

A lot of baby’s swimwear has full-length sleeves. This is to protect the arms from too much exposure to the sun. Many toddlers have sensitive skin and too much time spent in the sun can lead to sunburns. To keep them safe while out and about in a pool or a beach, long sleeves help.

Q5. What does a 6-month-old wear swimming?

A comfortable swimwear or a bathing suit is recommended for 6-month-old babies along with a swimming diaper (Disposable or reusable) which protects from any leakages or accidents. There are many types of baby bathing suits available. You can choose from all-in-one bathing suits or 2 piece swimwear as per your baby’s comfort.

Q6. What happens if a baby poops in a swim diaper?

If by any chance baby poops in the swim diaper, it remains protected in the diaper, saving you a big embarrassment. Swim diapers (whether disposable or reusable) are designed to create a seal around the thighs as well as the waist, protecting any accidents from happening.

There is nothing to worry about, just take your baby away to the changing room and change the diaper as you would normally do if they pooped in a dry diaper. Always carry a few extra diapers and swimwear for your baby in case of any mess.


Being adequately prepared with the right beachwear for your kids can ensure a fantastic time while they stay safe in the water and under the sun, for your next holiday. Shopping around and making the right choice can help you make a good choice and save you some bucks too. More expensive doesn’t always guarantee the best option. Choosing the right type that fits your baby’s needs is important.
