Ds has just turned 7 mo and has started bf pretty much round the clock. At night he literally won't sleep without a boob in his mouth. I have been trying to offer solids but he's just not interested- he will maybe manage about 2 small mouthfuls a day if that. I'm not sleeping, he's not sleeping unless being held by me and I can't do anything with my dd He won't take a cup or bottle either. Where has it all gone wrong??
