Glad everything turned out okay Sarah!
I have three kids but most of the work comes from the younger two. My 10 year old is great, the most I have to do with him is homework assistance and just making sure he doesnt feel ignored or looked over because of the two younger kids. So me and him have been playing the wii together. I think Just dance 3 is going to whip me back into shape lol.
I dont think adding on one more would be too much more of a challenge. Jen I think that statement is pretty true, after the first two it gets easier.
