My 3 months old baby has a red perineal raphe and in place it goes inside the anus it has changed the colour to white. When he was 7 weeks I have switched to formula, and week later he has beed diagnosed with reflux. He gets now a 10mg Ranitidine 3 times a day. After first week of treatment he started being constipated once in a while. At the moment his stool has a form like normal adult's one, but soft. He also seems like having difficulties while doing it - becomes red when he is pushing and cries straight away. Shall I go to my GP to consult this redness or it is just irritation which will get better? Thank you
