When my twin girls were born, I had a 2 year old boy and a 1 year old boy...so, 4 kiddos ages 2 and under. I learned quickly how to get organized. I loved the rocking chairs that vibrated and turn into toddler rocking chairs (someone else mentioned these and my girls still like them, BEST investment!) When one of my girls woke to eat, I woke the other. Honestly, they were easier than my singletons. Sounds hard to believe, but having them on a schedule from the start really helped, and they were unusually great sleepers.
Get help if you can! I did it on my own and was so very tired especially after having a c-section. Try to have everything as organized as you can. Have all your diapers, wipes, creams, etc. all right where you need them in each room that you'll be changing them. I had an organizer in their room, in our bedroom, and in the living room. (actually, I still have a shelf set up in my living room with diapers, pull-ups and stuff like that) for our newest baby boy who just turned 7 months old. If you formula feed, make a big container of formula in the morning to keep in the fridge and warm up as you go so you aren't constantly making bottles. I'd have onsies and outfits set out in advance...anything and everything to be prepared. I'd take a couple hours and just try to get things ready. It's my saving grace even today with 5 young children!!!
Good luck...it'll be such a fun ride! Enjoy your time with them and takes lots of pictures because the time will just fly by!
