Up until about a week ago he was sleeping pretty consistently through the night, waking between 6 and 7 (I'd wake him at 7). He had a 45 min nap in the morning and then between 1hr 20 and 2 in the afternoon.
Suddenly he is only doing 40 in the afternoon. Our childminder has had success getting him back to sleep and if this happens he goes for around 1hr 45.
At night he is suddenly waking a lot, needing us to help him get back to sleep - the other night he was awake for 2 hours.
Any ideas? He is just starting to walk if thats relevant.
