Hi everyone I'm struggling with keeping ds 10 months sunburn free at the minute. I'm currently using superdrug's own factor 50 roll on cream on him but he's still getting tell tale t shirt lines and some redness, which is worrying me. We have a holiday abroad for our wedding coming up at the end of the month and I'm terrified he's going to burn while we're away. Does anybody have any pearls of wisdom? He's at the crawling everywhere stage so our uv tent is somewhat unused and he wrenches a hat off his head within seconds of it being put on. 
I've looked at suncream recommendations and ultrasun keeps being mentioned but from what I can see from their product ranges they only do a family spf 30 or an extreme spf50 which has no mention of it being specifically suitable for children or babies. Is factor 30 ok for a baby or is not enough?
Thank you
