This National Holiday, I went for 7 days vacation. I had 15 packs 6 oz ice milk for twice per day and his was 10.5 mths.
Beside of the reserve, u should consider how to maintain the supply after the vocation. If u want to continue to feed him, u hv to maintain the pumping which is very technically if u want to bring the ice milk to hk. Pls check my previous post for detail instruction. Good work!
