My 8.5 month old has never been a good sleeper but his latest trick is to stay up in his cot chatting and giggling to himself for up to 2 hours in the night. I just ignore him but it's very hard to do and I'm wondering if anyone has experienced this before? What's the best way of dealing with it? It's often after a feed and can happen up to twice a night which obviously means he's missing out on a substantial amount of sleep. Thank you
