Your office got freezer? I tried to use the ice pack for Medela Freestyle. Once reached to office, put it into company freezer and only take out once I pump the 1st bottle of milk. (abt 11am)
Then can last until I went home (abt 8pm).
Fiona_mama, my company has a small single door fridge, but not function well/ not cold. If the Medela ice pack cannot keep for 12 hours, I'll be in trouble...
By the way, do you know whether FTG can keep that long?
