Hello, thank you for your reply.
My dd is now 22months old (will be 23 months old on Monday).
I took your advice and have tried pushing her nap back. She seems quite tired at about 1130am but can keep going after that time. The problem is that she now goes down to nap fine and I think she has fallen asleep and after about 20mins she is wide awake and doesn't have a nap at all for the day. For a girl who used to nap for 3 hours, I think no nap is not good for her and she is obviously tired from about 5pm.
I try to put her down for a nap at 12noon. I have also tried 12:30 or even 1pm but non of these times work.
I would be most grateful for your advice as I want to get a bit of schedule back especially as dc number two is due in 6 weeks! Thank you!
