Roisinsmummy, you said you try to put her to bed at 9am, 12.30pm and 3.30pm ? How much does she sleep after you put her down at those times? At 5 months my LO could only handle 2 hour A times. So if she is only sleeping for 30 minutes then I would put her back to bed 1.5 hours later. The crying when she nods off tells me she is definitely OT, I went through the same with my DGS and it still happens at 6 months. I do feel your pain as I just now got DGS down for an OT nap and am hoping for longer than 30-45 minutes rest. Anyway, the most important thing to look at his her awake time. Maybe if you posted your day in EAS format, we could get some more input
