So our almost 15 month old girl is on one nap now (for almost two weeks now) and we made the transition as she was showing signs she was ready (e.g. naps were becoming shorter, resisting naps etc). We were doing ok and she was having early lunch at 11 and down by 11.45 and was doing 2 hours sometimes a bit more. The past few days she has only done maximum one hour and is waking screaming and will not go back to sleep. Clearly overtired. Morning wake time we get her from her cot at 7am but she can wake much earlier than this (even as early as 5.30am) but is happy in her cot until 7. I have tried a cat nap later in the afternoon but it doesn't work and she won't go down for it. Any ideas? I don't really want to go back to trying two naps.
