For those of you who are feeding your bb with EBM, can i ask if you store the EBM in glass bottles in the fridge? And when you heat up, do you heat up the milk in the glass bottles directly, or pour into the milk bottles then heat up? I hv been heating up the milk in the glass bottles directly, but as the capacity of the glass bottles is only abt 120ml, so wondering when my gal's appetite increases, shld i pour into the milk bottle then heat up. Cos i notice that when you pour out the milk from the glass bottles when it is still cold, some residue is left behind in the glass bottles. How abt when milk is store in milkbags, do you heat up the milk first then pour into the milk bottle, or pour into milk bottle then heat up? Very confused what is the best way to do this. Can share what you do? Thanks!!
