Help, my nine month old baby goes to bed at 7pm no problem but then wakes up at 4.30am each morning. I have tried feeding her then putting her back to bed, but it won't work, tried leaving her to cry to see if she goes back off but still no good. So she has her first nap of the day at 7.30am!! Any ideas on how to stop this and cut out the 7.30am nap???
