My 9mo old DS sleeps well through the night (7-6ish on a good day) (I know I'm lucky with this) but will only nap for 35/40 mins at a time in the day (around 9.15 am and 1pm). He's dropped his 4pm nap and he really suffers trying to get from 1.30ish wake up from second nap to bedtime. He wakes up grumpy but cheers up soon enough but from 4 pm it's a slog to stop the grizzling. I expected the lunchtime nap to lengthen... But it hasn't! At the nursery he will be starting in February they all sleep for 2 hours at lunch. Will they magically sort him out?!? I feel for him, he is so knackered at the end of the day that tea and bath are a bit miserable. Poor thing. Any clues?
