My DS is 5 weeks tomorrow and is ebf. He often gets niggley when he needs a poo but tonight he is really distressed. It's not constipation as the poo is soft and runny when it comes out but he just seems to struggle to actually go. He's been screaming for a couple of hours on and off now and I'm sure that's what it is - legs keep going out straight which is what he does when he poos. Please please can anyone help with a quick solution?
