I'm pregnant with my first and due in March.
Hello, and welcome!
Hi and congrats on your pregnancy! I'm pretty new to this myself but I can share what I've learned about some of your questions from my limited experience so far. I've only been doing it for two weeks but with all the sleep deprivation that comes with a new baby, it seems like a lot longer.
-How long does it take to pump with a double pump?
I'm renting a hospital grade pump (Medela Symphony) and I normally pump from 10-20 minutes. I could probably keep going but my supply far outstrips demand and we've run out of freezer space until we buy a deep freeze so I normally do at least one 20 minute session a day and the other ones are shorter.
-How do you time your pumpings with feedings?
I really don't-I just leave part of every pumping out (it's good for quite some time-I use the 6 hour estimate). I'm normally two feedings ahead by doing that. I am very lucky and for the time being, both my husband and I are on full time baby duty so we feed her as needed from what is out. This could change once I go to work (or if my husband stops working from home) and it would obviously be trickier if you don't have someone to help. I don't pump on a strict schedule because I'm not good with keeping to one-I just get my 7-8 pumps in whenever is convenient.
-All day outings:
Today I tried this out for the first time with a family get-together at my aunt's. I just used my hand pumps and packed a cooler bag with ice packs and my supplies. I went off to the bedroom as needed and it wasn't too big of a hassle but obviously this is a far cry from a public place like a zoo. I'd probably do something similar with the small cooler bag in the stroller for a public place and use a nursing space if available. You could also carry your supplies and pump relatively inconspicuously with a nursing cover on an out of the way bench or secluded table. Because I just focus on getting the pumps in and not sticking to a strict schedule, I have a little more flexibility ie. I could hold off until we found a suitable place. You really shouldn't go more than 5 or 6 hours without pumping so obviously the flexibility only goes so far. Really, I can't imagine myself up for an all day museum trip with a tiny infant so for the first 12 weeks when you have to maintain a good supply and keep up the pumps pretty religiously, this may never be an issue.
