rice in the bottle

My daughter is 10 months old, and I am DESPERATE to have her sleep through the night. She falls asleep with no problems, but she wakes up about every 2 hours every single night to eat. She eats about 20-24 oz of formula during the day, and she gets two solids "meals." I feed her a meal of oatmeal and veggies about 2 hour before bed (enough time to get a bath and read a story or two) and right before I put her down, I try to give her 6-8 oz of formula.
