My 6 week old baby is really struggling to poo. She was going 5 times a day, yellow and seedy, then literally just stopped and didn't go for 5 days. She has been really struggling with wind and been farting a lot and it has been smelly. Today she finally pooed and it was yellow and thick, like korma. Is this normal? Is there anything I can do to help her go more regularly again? She is ebf, could it be something I'm eating?
