I recently met my birthmother. It was an amazing experience!! I'm slowly being introduced to members of her family. She has told her two older children about me but she has a 6 and 8 year old who have seen pictures but don't know about me at all. She wants me to meet them and she wants them to know me. However, she has no idea how to go about telling them about me because of their age and level of understanding. I tried looking for a book that might help explain things but all I found were books geared towards the child that has been adopted. It's a lot of pressure for her because she's concerned that they may not understand, might feel like she's been dishonest, they don't know anything about sex and assume that babies happen when people are married...so really it's not just one thing she'll have to say to them. Any suggestions??? Thanks!
