Not really but I have some experience with multiple children. No I didn't have them at the same time but the first two were close enough (1 year 16 days apart...not that Im counting).
Her Bad Mother, Mrs. Chicky, and Mrs. Chicken about to have a second child and are in desperate need of assvice. I'm more than happy to give it.

-I can almost guarantee you that they won't sleep at the same time. Darn those internal clocks.
-When the little one gets bigger and can sit on his own, bathe them together in the tub. Nothing like killing two birds with one stone. Yeah there may be more of a mess, but just think green in that your saving the planet by reserving our dwindling water supply.
-If they are the same gender than you will have to purchase two of almost everything. Toys primarily, sometimes underwear. Yes they will fight over anything. Purchasing one box of sugary cereal with toy inside, Im sure you guys would never purchase sugary cereals with toys in them but if you do, be sure to hide the toy until you have enough to disperse for everybody.
-Grocery shopping. For the love of your sanity beg and plead to have your significant other stay home with one kid or the other. If your lucky both. It's a war out there. Shopping carts, candy aisles, toy aisles, people in general, and two or more children in tow is a guarantee for surrender of your sanity.
I'll leave it at that as I could go on and on.
Good luck and may the force be with you.
