What do you think - a growth spurt?

4 months is the age of a big growth spurts for babies, so I'd say that's what it is. I don't think yo could fit in another feed considering you're feeding roughly every 3 hourly anyway. Unless he's hungry of course. There's not really a lot you can do except ride it out. We're going through the same thing with Emily. Just be assured that growth spurts don't last forever.

My DS did this around the same age too, he'd been sleeping through since he was 10 weeks old and then around 4.5 months he started waking during the night and hasn't slept through since! (now 9 months old!)
He does however settle pretty quickly with a quick bf these days but for a while there he was taking a full feed.
It will get better

We got told at mothers group today to expect a growth spurt at around 4 months and for our bubs to stop sleeping through the night when it happened.
