Until he was 6 weeks DS2 was constantly pooing and I was battling with nappy rash. Around then his poo changed to be thick mustardly coloured. Recently at 18 weeks its gone greeny, even pale, smaller amounts and his nappy rash has come back. I can deal with nappy rash but wondering about poo?
He was sleeping all night but last week hasn't been great although last night only one night waking which is ok.
Any ideas on whats causing the change in poo?
