He's been on the boob constantly - not a break without screaming - for past 3 hours. Don't think it's growth spurt as he had that last week. In general he seems to want the breast a lot - I think at least some of it is pure comfort sucki g and not sure I want to be a human dummy! Am exhausted - bad night last night and tonight shaping up to be worse - he won't stop sucking for a minute and doesn't seem sleepy. He has barely slept all day. So close to giving him a bottle of formula!
