Timing timing timing

We've been talking about having no.3. I know, I feel crazy just saying it.

We've always wanted 3 kids. We have our girl and we have our boy, people say to us that we can stop here now... but it feels incomplete, in our minds we still have no.3 waiting to join our family.

Our original plan was to have 2 year gaps between kids. So far so good.

But we keep coming back to when to have no.3, as the timing seems to coincide with when we had originally planned to leave for Africa...

We've even discussed the possibility of getting pregnant now with an 18 month gap between Lucas and he/she. Yes crazy.
Or having no.3 later and have a 4 year gap.
Or get pregnant while we're in Africa and possibly even have the baby there! I like the sound of an Australian Chinese born in Africa! :o)

Here are a few scenarios we've discussed so far. Haha...multiple choice for God, or he'll probably choose 'none of the above'!!
