My DD is 20 months and for the last 6 months or so has been very happily taking an hour daytime nap in the afternoon each day while also going to bed and sleeping 11-12 hours at night. Lately she has been still taking her daytime nap but will stay awake in her cot for 1-2 hours after bedtime just singing or talking to herself, does not seem tired enough for bed. So my question is do you think I need to drop her daytime nap? It seems a little early to do this as she is only 20 months old; or should I extend her going to bed time so that she is properly tired enough to go to sleep straight away?
