Okay I know 8 months is too young to start going off formula. With that being said this is just for future reference

so no bashing, DD is still getting 21-28oz of formula a day with purée food too

DD loves her purée food and oatmeal. I mean loves them! Since she gets them the same time each day, there are times she will refuse a bottle until she's had her food. We are only on food twice a day, but im starting to think she needs another small serving in the afternoon.
So my question is, when do you start decreasing the intake if formula and increasing the intake of food? Plus when do you introduce milk? She has had ice cream and cheese before (milk products) but I assume that's def not the same.
TIA
Re: Formula to milk?
My LO was eating 3 meals/2 snacks a day at about 12 or 14 months, with 3 cups of milk and as much water as her little heart desired. I would say that's probably your general age from my DD as well as seeing many other babies as a daycare teacher previously.
