FAQs about Swimsuits for Kids

  • 1. What kind of swimsuit is best for kids?

    There is no one type of swimsuit that’s better than any other. Whatever swimsuit your child is most comfortable in, both because of the fit and the style, is the best one for your child. However, when your child is younger, swimsuits that cover more skin will be easier for you, so you don[‘t have to worry about slathering sunscreen everywhere.

  • 2. At what age can kids stop wearing rash guards?

    Kids have sensitive skin and sun protection is essential. Sun damage can cause lifelong issues, plus, sunburns just plain hurt! It’s imperative that you keep your child protected with either rash guards or sunscreen. Rash guards are best for babies and younger kids because it’s safer than using sunscreen, which is usually full of chemicals. However, there are plenty of natural and non-toxic sunscreens on the market these days, so you can transition your child out of a rash guard whenever you feel comfortable.

  • 3. How should a swimsuit fit my child?

    Finding the right fit for your child takes a little work. You don’t want a swimsuit that’s too tight and uncomfortable for your little one. However, you also don’t want one that’s too loose because it can sag, drag them down with the extra weight, or fall off easily. You’ll want your child’s swimsuit to be pretty fitted, without being uncomfortable.

  • 4. What should I look for in a swimsuit for kids?

    As long as you’re getting your child the right size that fits well, that’s really all that matters. If you’re worried about sunburns, there are plenty of suits that are UPF 50, offering extra protection. You can choose long sleeve rash guards for both boys and girls to keep them covered. If you’re fine with slathering on sunscreen, you can choose whatever style your child likes.

Conclusion

The right swimsuit will have your child playing in the water all summer long. Whether you’re looking for a one-piece, adorable two-piece, or just some affordable trunks, this list has something for everyone.
