Hey mama's just wondering if anyone knows what this rash is? My little dude is almost 5 weeks and this popped up on both of his sides last night....he's gotten heat rash around his neck before cause it's really hot where we live so I'm not sure if it's that? also We just started giving him baths every night for the last week and half, he LOVES it and it calms him down before bed, but I also read that can dry the skin out/possibly be eczema? (I just google like crazy lol...and I've been giving him massages with Johnsons baby bedtime lavender lotion the last few nights so I'm wondering if maybe it's that? I'm just super paranoid it doesn't seem to be bothering him at all, he hasn't been acting any different but it looks really bad and I'm just wondering if anyone else has any ideas on what it is? I didn't do the bath or lotion tonight incase that is it, but I just want to figure it out for the poor little man :(Â
