Hiya my son is 2 weeks old today. I have been doing 50/50 feeding and giving him expressed breast milk but he seems to have completely gone of the breast milk. I've noticed over the 2 days when he pooing he's really straining and very uncomfortable. He is pooping regular but today it seems to getting worse and he's just getting more uncomfortable each time he's trying to poo. Has this happened to anyone else does anyone know what it I can do to help please?
