This was exactly what DS2 was doing - he will be 1 next week.
I hacve just cut all night feeding (gradually) - so he now has afeed if he wakes around 5am but thats it. it immediately helped his sleep - we do cuddles (DH notme as he dives down my top if i pick him up), patting, holding hand etc to sleep...
it has worked here - I wont say it was easy and he still wakes a few times in the night but he does longer stratches overall...
