My baby is 4 weeks old and keeps going bright red, looking like he's straining and then starts crying briefly then back to normal. This mostly happens when he is napping in the day. I assumed it was when he was pooping but every time I change him after this happens his nappy Is just wet nothing else. But then when he does dirty nappies he doesn't strain and it's soft so he's not constipated.
Has anyone else had this? Is it normal? He can do it 4/5 times in a row! Hoping for some tips to help him?!
