I have to go on a work trip to Europe when my LO will be between 4 and 5 months old. It will be 5 days, counting travel. I'm afraid it's going to be a bit of a nightmare if I'm still breastfeeding by then, which I really hope will be the case. I know you can buy adapters to convert 110 volts to 220, but I've heard that can really lower the power that the device puts out - just curious if anyone here has experience using their 110 volt pump with 220 volt power and an adapter? I should be able to pump regularly, but my biggest concern is that if the pump power is sufficiently weaker, it could lead supply to plummet... This makes me think that maybe I should just see if my MIL can come to watch the baby while I'm working and bring him along, but that also seems like a big hassle/expense...
