Haaka help!


So I just got a haaka. And I was wondering if I could leave the milk in there and use it again within the 4 hour time frame before I put it in the fridge. I’m feeding every 2 hours right now so can I just feed twice before I transfer it into a bag and in the fridge? Any other advice on how to use it would be appreciated too! I need all the tips on how to build a stash before I go back to work!:)
