Breast milk

Amie
Hi moms! So my daughter is 3 months old and refuses to take a bottle (I'm ok with that) but I produce so much milk that we had to buy a freezer for my basement!! I started pumping when she was born incase I decided to switch to bottles, but it doesn't look like that's going to happen. 
So my question is, what can I use the breast milk for? When she starts food, I plan on making my own food. Can I use it in the food? Thanks for your help!
