Or growth spurt?
My LO was doing so well, settling himself to sleep and sleeping through to 6.30ish. And then out of nowhere, he started waking up again around 3/4am and yesterday had a good old cry before falling asleep.
I am pretty sure he was not particularly hungry when he woke up at 3.30 last night (he had a dream feed at 11pm and eats well during the day).
I was just wondering if other people experienced something similar.
