So my daughters pediatrician switched her formula from similac advanced to similac neosure. My baby use to drink 4oz with the similac advanced formula but now is only drinking 2-3oz with the similac neosure formula.

Does anyone know why she eats less?

I'm thinking because the new formula has more calories, but I'm not sure.
