I'll start going to work next mon and wondering if I need to buy a proper cooler bag for storing the milk when I travel back from office to home. It takes me about an hour from office to hom that not sure the milke is still ok.
Can I just buy normal cooler bag ( those for picnic ) or should I buy the proper one from Medela ( HKD about 300 )?? It's quite pricy!! Any other suggestion?
