Liquid intake

I took away my daughters bottles and she’s not EVen missing them. However there is no way she can possibly get down two cups of milk plus water in one day. It is just not realistic for her. The only way to get her to drink more is by putting the milk in a bottle but that defeats the purpose. Another issue is when I was mixing formula with milk she was extremely constipated even with feeding prunes etc. so that was a whole other problem.

Maybe I am stressing too much over this?!?
