Just a vent....I guess :)

Is it possible she has incredibly (like non-existent) self-esteem and does everything you do because she feels she has no ability to do anything on her own? Maybe she was raised in a manner that she never (like ever) had a chance to think for herself or act on her own and now she is clueless if not following someone else's lead?

Is she married?

I would find this so incredibly annoying, but I have to admit that reading it I was laughing out loud because it just sounds so, toddler like!!! I can totally see having side by side daycares and having the neighbor trigger some ideas...like hey wow it's beginning of April and I don't usually bring out the slide until May when the weather is nice but its warm and those kids are having fun so let's bring ours out too. But this is clearly more than that!

I also agree with having your stuff out, waiting until she comes out and copies then quickly switching...which you are both out to see if she switches in front of you. This would be just for kicks though...to get a chuckle if she copies (or stands there confused at your changes lol).

I really don't know what to suggest. There really isn't much you can do. You can talk to her and tell her you don't like being copied...but it's her house, her stuff so she can technically bring it out when ever she well likes. Really not sure what to suggest. Move??
