Manual pump recommendations? I'm heading out of town for four nights in December. DD is 20 months and is only nursing twice a day (first thing in the am, last thing before bed), but I'm not ready to wean her unless she wants to, so I'm going to get a manual pump to bring with me. At Target today, I saw that the Medela one is way more than the other one (Evenflo?), but I already have the right size flanges and bottles for the Medela. TIA
