hi there, my 9 week old has just in the last 2 nights began waking every 45mins/1.5 hrs after his first wake up and feed which was usually between 1 and 3am. this has got earlier, midnight/1am ish. he hasn't napped properly (whatever that is) for the last 2 days - I don't know if he's overtired/undertired or just having a phase, but I cant seem to get his awake time right. I've tried 1hr, 1 hr 15 mins, 1.5 hrs, 2 hrs put him down awake/sleepy but awake - might drift off for 30 mins then wakes up. i've tried leaving him, feeding him - but he then falls asleep feeding and if I put him back to bed he wakes right up. I know sleep patterns change a lot, but he was sleeping what i'd consider a good amount during the day and only having two night time wakes previously. If I didn't have a toddler running around I'd just lie down with my baby and have a sleep myself but I just cant this time round!
any advice/ideas greatly appreciated. thank you
