Hi N. -
Congratulations! I wont lie, this will be tough because the kids stages are going to be different for 2-3 years. My kids are 11 1/2 months apart. True Irish Twins! It wasn't planned, but like you since I was older, I was ok with it (after I got over the shock!!)
When you get home, it will help to have some one there, maybe not staying over but helping you out. I would also try the bassinet until you know how child #1 is going to handle the outside noise, and how child #2 sleeps (or doesn't)
You most likely will have about 2 years of hell because of the different stages that they were in, but now they are the best of friends, well, they were up until about 2 months ago...now they are 4 and 5 and are fighting like cats and dogs!
Its tough, but worth it!
Good luck!
