CONGRATULATIONS! In my experience, the 1st 3 mos might be a blur, but how wonderful it is to raise twins! Best wishes to you!
I found that feeding them at the same time worked best - otherwise 1 breast leaks too much while feeding the 1st baby & you feel like the 2nd baby doesn't get the same amount (then you've got mother-guilt). You just have to give up doing ANYTHING, sit on the couch with pillows on both sides, & (while there are different ways to place the babies, what I found worked best for us was...) place them head-to-head with their bodies tucked up against your sides so your arms can keep them close while you hold their heads. It's a little bit of a balancing act to get used to & not altogether easy to do by yourself, but take your time & try not to rush through it! I did have a twins Boppy-type pillow - it's wider to support both babies, but two pillows worked just as well - whatever you're comfortable with.
Sit back, relax, close your eyes & enjoy it while you can, because it really does end too soon (to me, as much as you want your own body back, it was sad to give up that particular bond - I nursed them for almost 15 months). And do pump when you can - it's always helpful to have the extra available when you need it. They will eat A LOT & eventually you will probably have to supplement with formula (even if you feel like a milk factory!).
When your husband is home from work, he can bottle-feed one while you breastfeed the other. Daddy has to help & has to understand that this is an incredibly demanding responsibility you are dealing with all day long - share with him that you need a break sometimes, because it IS a job - a very stressful, very emotional, 24-hour/7-day job.
It WILL get messy, it IS demanding, you may cry sometimes from being covered in milk, spit-up, pee, etc., but you will get thru it! As far as the job goes, I hope you can work that out - I though I'd go back to work when mine were 4 months old, but they are 8 YEARS old now & I spend a lot of time volunteering at school! The cost of childcare vs. my paycheck didn't make sense; maybe you've got a different ratio there - good luck with that.
BEST thing I was ever told was when you have people over (or are someplace crowded) - take the time to feed them in PRIVATE - it will be the only quiet time you get, especially during the holidays! Close yourself & 1 or both babies behind a bedroom door, close your eyes, take some deep breaths & ZEN yourself for that 10-20 minutes. You will need it. Some people will want to come with you to "keep you company" & will just yap the entire time, but you need down time & space, so take all you can get in those busy situations.
BUT, also accept all the help people offer during the day! Someone's going to the store & offers to pick up your groceries? WONDERFUL! LET them help you. Let someone else pick up the holiday gifts & wrap (or at least help wrap) them. Let them vacuum your house, do your dishes, your laundry - you cannot be Superwoman, and the offers will dwindle soon enough!
Also, turn off the phone ringer when you're taking a nap! You can get the Foamies door hangers in red & green to hang on your front door (you might note on the red "Taking our naps - please don't ring/knock"). I had a pop-in visitor that ignored all signs though - hopefully you don't know her! :)
Good luck, best wishes, peaceful sleep, easy babies, helpful family/friends - I wish you all of these things! Congratulations again!
