DS weighs 28 pounds, so he is a little bit on the larger side. Okay he is huge 
, he is off the charts for height and weight. I'll give you a typical day's schedule:
Wake up around 7:30: granola bar, yogurt, fruit and a sippy of milk
10:00 cheese cut up, vegetable baby food (small jar)
10:30- nap
1:00 wakes up and has a PB&J sandwich or something of the sort and fruit with a sippy of milk
3:00 more fruit or vegetable baby food and cheese
6:00 meat, milk, and some type of side dish like vegetables or pasta.
7:30 bedtime with 4-8 oz bottle depending on how much he drinks before falling asleep.
So he drinks 4-8 ounces of Good Start formula per day. He drinks about 8-12 ounces of milk and probably another 8 or so ounces of water or watered down apple juice.
