DD is almost 3. We talk to her about adoption when it seems the right moment, although it often feels a bit "clunky". We have some age appropriate books that we read occasionally as part of our bedtime routine.
As her nursery worker is pregnant, it seemed the right time to broach babies in tummies, and I talked about her not coming out of mummy's tummy.
Today she has asked for a little sister (!) so we talked again about babies in tummies. She then asked to look at the photos where DH is feeding her yoghurt as a baby - this was during intros week (2 years ago). We also got out the photo album that her FC made her and talked through all the photos and she asked about who her FC were, which I explained again. We do meet up with them about twice a year. She was really happy at looking through all the pictures, and wanted me to go through them all a couple of times.
Does this all sound okay, too much or not enough? She is a bright little girl, but I don't want to overload her. I know she has been with us two years, but I feel like such a beginner to all this sometimes :)
