DS is drinking out of a sippy cup consistantly now. I give it to him four to five times a day at meal times and snack times. Is it okay to put it back in the fridge between two of those times and give him the same milk in the same sippy cup twice? He backwashes quite a but. I am super OCD about food contamination and such but I hate how much milk I waste and how many cups I have to wash if I don't. DS was breastfed and never took bottles so all this is new to me. I know you weren't supposed to reuse breast milk or formula but I am not sure the rules on WCM. Thanks!
