Just posting for a quick response. I started trying my 13 mo on 1 nap yesterday, after she's been needing much longer awake windows and two naps was getting tricky, plus waking up earlier. Yesterday we tested it out as she was up teething in the night (normally sleeps through) and woke up unusually late at 8.30am. So I seized the opportunity and gave her one lunch nap which worked out fine. She went to bed at 7.45 and slept 12 hours.
Today I have kept her up but stupidly made the mistake of going for a walk in the buggy at 11.30. We don't have a garden and it was getting stuffy indoors. However, of course she fell asleep at 11.45! My fault.
Question is, what do I do now? If she wakes at 12.30? I cant let her nap after 3.30 or we will have a difficult night.
Lesson learned about taking her for a walk when she's tired!
