Talk to General Problems on Skin Or Blood

I saw these marks on the back of my 10 months old daughter. I want to know if its ok or not. It was not there earlier. Just find out last night. -there is no pain if pressing. -the babies behaviour is totally fine. -only the mark near the pamper was there since her birth which is birth mark according to the dr rest all are just find out last night and those are still there. -no, these are not finger marks, i tried holding her hardly and slapping if such marks increase but no. - its not the colr of her cloths because she wears light colrs light white, peach, yellow recently. -i dont want anyone other to see her pics except the dr.
