Just wanted to subscribe, DS is doing the exact same thing, he has always been a champion sleeper and would sleep 10-12 hours straight no questions asked, but in the last few weeks he's been harder to get to sleep to start with and generally wakes again at about 10pm and needs soothing back to sleep, then on some nights he'll wake several times during the night or sleep through til 5am instead of the usual 7am. Same thing, no obvious discomfort, nappy is fine, he's not teething (though we do give him bonjela JIC) is room is a comfortable temp as is he and it's still dark. He's also fine to go back to sleep being held but is histerical if we leave him in the cot or try to put him down before he's completely back to sleep. I can't stand him sleeping with us coz he punches and kicks and wriggles and it drives me nuts. Sorry for no advice, but you aren't alone! Someone help us lol
