What is the deal???

Heather

I don't know what to do. 7 months old this week. Gets cereal and solids (we do one a week). Takes 2 naps during the day. She has always had bath at 8:30 and bed at 9. Drinks 6-8 ozs before bed. She will fall asleep, but will wake up 30-60 min later ready to PARTY! Stays up till between 12-1. Then still gets up between 6-6:30. No teeth yet, and formula fed. She is clearly not sleeping enough, but what gives??? Anyone else???
