Hi so my little boy was sleeping 7-7 with a feed at 1/2am. Then he started sleeping terribly which I thought was sleep regression as he's 4 months old. He then slept through from 7-5am for a week which felt like heaven and I thought we'd cracked the sleep thing, but now we're lucky if he sleeps for 4 hours at a time. He generally feeds and is straight back to sleep but sometimes he falls back to sleep as soon as I pick him up. No idea what's going on and praying it's just a very quick phase xxx
