This is also something I have thought alot about latley, I only ever wanted 2 kids, but DH is one of 3 and said he always wanted 3. However, now that we are expecting no 2 I think that it might be it for us, there are several things that weigh on the decision, 1- we would have to buy a bigger house, 2- a bigger car, 3- I love my career and I would like to one day get back to full time teaching, but not untill my kids are much older, which wold be further away if I had 3, things like travel also play a part in our thinking, we would love to be able to take our kids travelling the world and just the extra cost of 1 more child might make this too hard.

Having said that things might change, and I never say never. I guess we wont truly know until we have had DS and see what life is like after that.
