Congratulations mommy!!!!
First: Accept any and all help that people offer. Start a schedule as soon as you can, so people will stay committed when they have something in writing.
Ablolutely join, confer, talk to, or search on the internet any advice on raising multiples and managed care in the beginning. Get lots of ideas, I found I went through a few before I really learned what worked best for our family..(remember what worked for some, does't work for all)
We, like some other moms, forced a schedule for a while. We did find eventually around 8 weeks one twin was "sleeping" better than the other and we let him rest longer... They will start to give you some clues, and sometimes through trial and error you will discover what works for you.
Eventually, we did end up hiring a nite nanny for 2 nites a week for about a month to get some rest. You may want to consider that or try to get people to volunteer for nite shifts. (family, friends??) IT WAS WORTH EVERY PENNY!!!
Take lots and lots of pictures! I am glad we did, because in the beginning you are in survival mode and wont really remember much (lol).
Get hand-me-downs, or go to sales for multiples (other moms of multiples sell there stuff for MUCH cheaper)
If someone is throwing you a shower.. ask for a diaper well. We had each guest bring a pack of diapers, any size or brand and it workd out wonderfully!
My boys turned 3 on Tuesday and we are having the times of our lives with them. It WILL get easier, and worth it's every moment. Rest well mama!
