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!
Personally I put it back in the fridge; BUT If it's not finished by the following meal or before bed time in the case of supper milk, it gets dumped, washed out and given fresh milk for the next meal. I only give her half a sippy cup at a time though, so it's usually drank by the end of the meal anyway.
