What to consider when buying swimwear for your baby
Depending on where you are planning on using the swimsuit you may want to have more than one option for your baby.
Some swimsuits and wetsuits are made of neoprene. They can come in various thicknesses which suit different seasons. The thicker the neoprene, the more effective the wetsuit will be at keeping baby warm. Also look for fleece lining as extra insulation.
Other swimsuits will be made of lighter materials which are stretchy and less restrictive than neoprene.
Good swimwear should be comfortable for baby to wear. They won’t want to feel restricted so finding something which is both comfortable and practical is key.
Ease Of Use
If you are going to be changing swim nappies, you want swimwear which isn’t too difficult to put on and off or has access for changing.
Look for swimwear with UPF protection of 50+, as baby will also be protected from the sun.
