Hi ladies, I'm looking for some advice and hopefully someone can help. My 9 week old is formula fed and hasn't pooed for 3 days now. He is clearly trying and is very very uncomfortable but can't go for some reason. Does anyone know how to help him? When he's gone 2 days before he's been very uncomfortable and the hv has said that it isn't constipation if the poo isn't hard when it comes out!! He has been 3 days now and he won't take a full feed because of how clogged up he is!! And he screams so much because he needs to go and he tries so hard 
Please can someone help?! Thanks!!!
