Baby's skin...

There's a big rash that Emry has broke out on his forehead, knees, elbows, shins....first I thought it was just dry skin, but it got worse after I put Aveeno on him. I always thought Aveeno was like one of the best things to put on a baby's skin but I guess not- some of it is dry patches, but we need to go buy some burts bees lotion or some brand that's completely natural. I'm afraid to give him his next bath until we get it, cause he skin always gets worse after a bath, cause that's when we put the most lotion on him. I love him so much, everyday is amazing with him!
