DS is 17mo. He naps for around 2hours in the daytime. Today he napped for 2hours 30minutes which I know he needed because each night since the clock change he has been grumpy but I wondered if I should wake him after a length of time. If we are needing to go out and I ever wake him (normally around the 2hours mark) he is very upset and cries. He has been waking early in the morning since the clock change but normally he sleeps from 7.30/7.45pm to 7/8am. This week it's been more like 7.30pm - 6am.
