Iwas having problems with my 4 mth old boy waking regularly throughout the night and only having small catnaps thru the day. After reading everything I could find and trying different things he is now sleeping 2 x 2hr and 1 x 1 hr thru the day and 7 to 7 with one feed at 4am.
What I did was start the day at 7am (even if it meant waking him) and giving him a bottle then I followed 2hrs up and 2 hrs down. At first he constantly woke after 40 minutes but i just spent a lot of time resettling him and eventually it worked. I even had trouble keeping him up for 2 hours so we went for lots of walks. After a couple of weeks he settled int this routine really well then the nights just seemed to get better. I know all babies are different I just thought this worked for me and maybe it would work for you.
