My MCHN said to use a suncream specifically for babies as it doesn't have a certain chemical in it that regular suncreams have that could be harmful to bubs. At the end of the day it is best to keep them out of the sun, wear light cotton clothing and a hat.

Sunsuits would be personal preference. DS has a swim nappy and a rash vest that zips at the front. Sometimes it's a pita as it rides up because it's slightly too big for him atm. But we swim indoors once a week, it's mainly just to keep him warm.
