Help- 15 week old forgotten how to sleep more than 2 hours in a row!?

[Newmom2b]

Sooo tired! My ds had just started stepping well, goin down at 7pm and waking for feeds at 2 and maybe 5/6ish. BUT now I'm lucky if he sleeps for 3 hours solid!! I presume he is going though the 3/4 month sleep regression.
My question is, do I need to 'reteach' him not to wake for feeds or will it happen naturally?
Last night I put him down and had his last feed at 7 he woke at 9.30 and I resettled him until about 10.30. He then woke at 1.30 but where I would have noramally fed him I resettled him until 2.30 where is woke gain and I fed him. He didn't settle and I let him moan (not full blown cry) until he fell back asleep ( was only about 5 mins.... He then woke again at 4.30 but I tried an hour of resettling him until I fed him at 5.30.
I thought it may be best to try other alternatives to get him back to sleep rather than always feed him as I don't want him to get into the habit.
What do you think?

P.s the waking up every 2/3 hours has been going on for 3 weeks!!

Bump...?

My DS did this from about 15 weeks, then all of a sudden started sleeping through. I'd say it lasted about 6-8 weeks (sorry!). We still have occasional bad nights with teeth etc. but he's mostly much better. We didn't do an awful lot different but he worked out how to roll over and usually sleeps in the recovery position now, which I'd never have put him in myself! So I think usually they sort themselves out, it's crappy going through it though.

my 19 week old has been doing this too for about 3-4 weeks hopefully she will settle soon....I am thinking that maybe when she starts some solids (BLW) in few weeks that she will sleep better, she is also rolling herself over now on to tummy and sucking fingers so that may help her self sooth too eventually.
