After looking at your pictures of your baby I don’t know how old yours is but mine has that red bump area to. He was never burned as I have been extremely cautious of the temp of feeding. Mine has that red bump on his middle neck. It is his neck area. He lays it consistently on a little stuffed animal I have in his brooder. It is just his neck area. He has had it since birth. He is 20 days old today!
