My baby's arms were really pink after being in the sun for about an hour yesterday. I had applied Factor 50 but, on doing further research (after the horse had bolted), I don't think the brand we're using (Banana Boat) is the best. It's excema-friendly but obviously not as protective as other brands. He seems happy enough but his arms are still pink and I feel absolutely terrible and sick to my core for letting this happen. He shouldn't have been in the sun at all on such a hot day. I know that now and feel very naiive. He's almost 1yo so I don't think we need to go to A&E. I used cool flannels last night to cool his arms and put on E45. Anything else I can do?
