Alternative to Suncream?

Hi,

As you can imagine the current hot weather has required lashings of suncream on the children; my eldest in 8 and has autism. She is extremely touch sensitive and has always hated most creams on her skin, but I think the combination of several hot days, lots of suncream and being sweaty and sticky has just pushed he over the edge today. We've had an enormous meltdown this morning, which is not great when we both have to get to work and get the children to holiday club (which she also isn't a fan of, so another contributory factor). I'm just wondering if anyone has any specific types of suncream that are less heavy or greasy or could recommend anything other than actual sucream?? We use Boots Factor 50 8 hour - for obvious reasons... she is a child and it's usually one application for the day.
