My son is only 5 months, but already weighs 20 lbs/28 inches long. He has been satisfied with 24-30 oz of formula every 24 hrs. As well as approx. 3 Tablespoons of a vegetable every day (Just started the veggies 2 wks ago). The past couple days he has been acting fussy which is not like him so I have increased the amount of veggies. Doing so he seems happier. Just wondering a baseline of how much solid food everyone else is doing? Or should I increase the formula. Thanks so much.
