What to transition to??

So my daughter is 14 months and still breastfeeding. She eats around 3 times a day. I go back to school in a week and will be gone an I don't have a huge freezer stash so I wanted to know what most of you mom as transitioned to? I'm still going to breastfeed On the days I don't go to school. I was thinking of doing some soy or almond almond milk or something organic instead of cows milk? She loves water but I'm just not sure if she's going to want something like milk throughout the day once my Breast milk is gone! TIA
