controlled comforting - anyone done it?

[Stargazing]

DS is 6mo, fabulous eater, big lad, has been on solids since 4 mths (just fruit & veg) and I've now introduced pasta, pulses, meat, fish in the last 2weeks, He weighs a good solid 9kg and breastfeeds well throughout the day. Has a bottle of formula as a 'dream feed' at around 11, has done so for about a month (this feed used to be a bf)

Problem - he wakes up anywhere btwn 3 and 5 wanting another feed. I think it is just habit, since he eats so well in the day etc - am sure he could make it from 11 til say 6 or so without having a feed. Besides which I a) am tired of being woken up, as I have an active 22 mo too, and am full-time mum to the to of them, no family on hand, no help etc etc and b) want to get my period back so I can start thinking about No3 ... cutting out the night feeds would help kickstart ovulation again.

enough with the background info!

Anyway, I am considering controlled comforting to get him to drop this early-morning waking up .. any advice? experience?

is he in his own room? that would help cut the night feeding down, thats what worked for my ds... i put ds into his own room at 10mths (and 10mths of 3-4hourly night feeds) and within 3 nights ALL night feeds had gone!! the first night as soon as he woke i went and fed him, second i'd leave him to stir for a couple of mins before going in and feeding for a shorter time and the third night he woke once and stirred for about 2mins then back to sleep!!

hmm. we live in a 2-bedder .... dd is in one room and obviously I dont want her woken by ds .... he sleeps in a cot in our room, but our room is massive so he is a fair distance away from our bed...

any way you could tie a blanket or something over the cot sides so he can't see you when he wakes so you can leave him for a while?? (obviously would have to be tied on tightly enough he cant pull it in and over himself....) then once he sleeps through with that then move him into the bedroom with your dd....???
