My 6 week old has a purple mark on his leg, his had a few scratches where he grabs the skin on his arms before that haven’t faded under a glass but can see they are where he has pulled his own skin (his a grabber) this mark is on the bottom of his foot it’s really faded and slightly goes under glass, I’m suffering badly with postpartum anxiety and didn’t know if anyone else’s little ones get random marks , he kicks his legs on to one another so wondering if it’s from that, I did ask the drs and he didn’t seem concerned I was getting worried about petechia but he said that certain rash comes as a group ? Also he currently has bronchiolitis confirmed by dr
