DD is only just 18 months and just before she stopped napping entirely. She was doing 45 mins to an hour waking at 2.30pm previously. I've tried making the nap earlier but no difference. She doesn't seem remotely tired and will happily go through 12/13 hours awake before bedtime. I'm still putting her down for a nap but mainly she spends it playing in her cot or crying so I'll come back. Has this happened to anyone else? Should I bother putting her for a nap anymore? She doesnt sleep brilliantly at night either so I'd have thought she'd need one still.
