What happend to my good sleeper!?

Katen is going through a major growth spurt. Overnight she grew legs! However, this growth spurt is interrupting her sleep because she's hungrier now. We're back to waking between 12:30 - 1:30 and again between 3:30 - 4:30 and every hour to two hours after that. Ug! Mommy got so spoiled. We have increased her bottle from 3 oz to 4 oz now and that seems to be keeping her more satisfied but not enough to sleep through the night again.
