My 6MO will sleep for anything between 30mins to 2 hours in her cot for her morning nap. When it is 2 hours, great and the whole day pans out nicely. When it's 30minutes it messes up the whole day. There is no chance of resettling her when she wakes from a nap, have tried this, but the result is that she is knackered again by say 11am, the time for her mid morning feed and falls asleep on my boob briefly and is then in no fit state for her new solid lunch at 12 and exhausted by 1 when she would normally have her second nap. Any experience of this and top tips?
