Wow I bet that was a shock. Congratulations on your pregnancy. I have 6 month old twins, but they are my first so I don't have any expierence in having other children as well. It is such a joy being a Mum of twins. Sure it has its moments that are a challenge, but it is such a fantastic feeling when you get to expierence all of the 'firsts' two times!!!

When we were doing our multiple birth workshop class before the twins arrived we were told about how some nanny agencies need placement for their student nannies. I think they normally do this when you have a few kids. (My sister is a nanny and did placement with a family with twins +1) Basically these nannies need to be out getting expierence with familes, it doesn't cost you anything because you are halping them also and you get some extra help. Perhaps look into that. Even if it was one day a week for a little while.

Good luck.
