Tara, my DD was 7.5yrs when we found out we were pg. We told her immediately.

Through unfortunately circumstances, DD has learnt about death. I've always said that someone/something dies cause it's too old, too injured or too sick. Very basic but very true IMO. I explained to her when we told her we were pg that we hoped that the baby would continue to grow strong inside my body until 40wk later it would come out. I also explained that it doesn't always happen like that. If the baby doesn't get strong enough or doesn't grow properly it's body can be 'injured' and it might die. We hoped it wouldn't die but we couldn't control what happens. She understood and accepted it well. Fortunately we now have a bouncing baby boy.
