Hungry girl

Was wide awake at 5am, think I was stressing a little about nursery. Managed to get Charlotte up dressed, breakfasted and back to bed for almost an hour sleep before we had to leave for nursery.
No tears when we got there, I just dropped and ran (I wanted to so badly to stay and check she was OK but knew this would be detrimental)
Whilst Charlotte was at nursery I went clothes shopping as none of my clothes fit. Three pairs of shoes, three pairs of trousers, three tops and two cardigans later I went to collect her.
There had been tears, but nothing too bad (certainly not as bad as previous time when nursery rang asking me to come and get her). She had had a sleep, played and eaten snack, but point blank refusal to drink ANY milk. This worries me soooooo much! Open to suggestions on how to combat this.
Came home and she polished off her lunch really quickly as well as a bottle of milk (phew).
