For me, it was a case of just "knowing" I wanted a third child. DH initially said he only wanted two, but without any input from me - other than me saying to him occasionally that I'd like a third - he came to me in agreement. This is definitely our last baby though - mentally I'm good with that, and physically I can honestly say I'll be happy not to go through TTC and pregnancy again.

I agree with dustmite. It has to be the right thing for you and DH, and not based on a whim. Just food for thought ... I'm not sure how old your other children are, but I can vouch that this pregnancy has been tougher mentally and physically just trying to deal with - and keep up with - a two and a four year old. I'm not saying that's the case with other women going in to a third pregnancy, but it certainly has been for me.

Would it be worth your while talking to a psychologist/councellor/GP just to try and have a clear idea of whether you do/don't want a third child?
