1) teething, could be.
2) not getting enough of food... umm, i guess the veg puree at evening helps her to digest faster. I remember I gave 1/2 bowl or 5 spoonful of cereal to my son in the evening when he was 7 months old and sleep till next morning at 5.30 or 6am for another feed.
3). too much nap? No, just right.
