hello, not much help, sorry, but my ds2 is 7mo and for about a month has been doing this. all but 2 nights in the last fortnight i have resorted to going round the block with him in pushchair at 10pm!
he has always been a rubbish sleeper too -at first, would only sleep in sling/with my nipple in his mouth co-sleeping, then we had about 6 weeks of waking every hour to bf. managed to break thatby moving him out of our bed into an amby hammock, and had a blissful 2 weeks of bed at 7.30ish, and two night wakings but he would immediately go back to sleep after a bf.
so now, it is bath, book and bf, but at the end of the feed he pulls himself off and smiles at me, kicks his legs and wants to play.
we have tried earlier naps/later naps/later bedtime/putting him in proper cot (just screams)/ walking round in sling/letting him play/putting on floor and ignoring/sitting in high chair whilst we eat/more bf before bed/less bf before bed. nothing works. occasionally he WILL go to sleep at 7.30-8, but i have no idea why, there is no pattern.
it is driving me bonkers, i have just gone back to work (3 days/wk), we are moving to australia for a year and also have a 2.4yo to look after (also just started sleeping badly!) so really need my evenings to do chores.
anyone got any ideas?
