I would agree google will drive you insane. I think they normal my LO has dimples on her knees, elbows and her back I think they are the cutest thing and so does her pediatrician she always brushes her finger over them and goes “hey cute dimples” lol obviously if you worried or want peace of mind let your pediatrician know
Pretty sure dimples are normal. Baby is just getting some fat on them. I wouldn’t worry…and don’t fall into the google trap
