He's been a pretty good sleeper in general, but we went on holiday last week (what fools!) and since then he won't settle for his nap or for bed. He isn't properly screaming but is warbling and grumbling and cries a bit, but it was 8.45pm by the time he went off last night, and tonight he's still grumbling now - I put him down about an hour and a quarter ago.
Today I put him down for his nap at 1pm as normal and by 2pm he was still not asleep so I put him in the car and he eventually went off about 20 minutes later for just over an hour.
I just worry that he's now in a cycle of being overtired, and the more tired he gets, the less able he is to go to sleep. Tonight I was really strict about his routine, started 15 minutes earlier than normal, quiet time before bed, stories, quick bath (which he hates now, used to love it - maybe overtired??), pyjamas, milk, story in the dark (no book), bed.
Don't really know what else to do! Can anyone help? It's really affecting me!
