My baby son is nearly 4 months old and I wonder if it is necessary for him to wear sunblock lotion when we take him out? If yes, can you recommend a brand? Thank you.

I think I waited till about 8-10 months before using sunscreen on my daughter just because I was uncomfortable with putting stuff on her skin. I just always made sure she was covered with a hat, sleeves, etc.
