She's 18 months and has now been asleep for 3.5 hours (day time nap). Usually I wake her after 2 or 2.5 max BUT this morning everything was wrong and I mean EVERYTHING. She was so grizzly and she has a runny nose which just won't go away and has been there since she was poorly a couple of weeks ago. She went to bed at 7pm and woke at 6am today. I'm torn between the fact that she might actually need to sleep and that this is a ridiculously long sleep.
What would you do?
