By 9am shes getting real whingy same with the 12 and 3 one.
I did a sleep school day program, and they suggested that by the time they get to whingy they're into overtired already where it can be harder to get to sleep and stay there.

Maybe you could try putting her down half an hour earlier?

Weird sleep signals they told me to look for were grabbing at clothes, a little cough, hiccoughs, a little vomit, movement then pause then movement, avoiding eye contact, then the obvious rubbing at eyes and yawning meant overtired was going to happen soon. They said the subtle signs on their own didn't mean tired, but 3 or 4 in a cluster could be tired.
