Depending on where you go, the UV stuff could be useful, could be useless. My DD spent four years in Bangkok. I seldom used sunscreen on her while we were in Bangkok, the pollution is so bad sun couldn't really get through. She did wear a two piece UV swimsuit because t makes nappy changing much easier. IIWY, I would just take ordinary clothes and use plenty of sun cream and a hat. Do take re usable swim nappies, if you rinse them out they will dry by the morning.
