What type of questions do you think they’ll ask. This is something I’ve never thought about. I also have nothing of my childhood. I have contact with my mom and sisters but not sure if that’s going to continue because of toxicity. I think being honest and saying oh this person isn’t in our lives because they weren’t very nice. Or if they ask about toys from your childhood just say you don’t have them anymore or that you played outside and didn’t have many toys
i think keep the parts of your past you don’t want to share very lowkey. i don’t know what it is specifically of course, but if they end up going down that avenue or get into situations you are familiar with, that’s the perfect time to share. i don’t think they’ll ever really realize mom played with toys until they’re much older anyways. but if you wanted to, get them a toy or something that ‘mom loved and always wanted this toy when she was a kid’ so they can make a past for you in their head
I don't think you need to lie to them, for your own sake as much as theirs. Kids understand a lot more than we sometimes give them credit for, and do tend to take things in their stride. You could say something like "Sometimes, very sadly, people have family that aren't very nice and don't love them as much as they deserve and that makes them sad. But now I have you to help show me what real love is, and that has made me so happy and all my favourite memories have been spent with you" 💚
