Finn will go off to bed at 6ish without a fuss at all. He's bathed, changed and fed and then he's pretty much asleep and has been sleeping through till 10 when he wakes for a feed. However the past few days he's been waking up an hour or so later with inconsolable crying! His dad can't get him to stop and I have to go up and either try to feed him again or cuddle him to calk him down. Any ideas? I'm wondering why this has suddenly started.
