I got home tonight to find my partner with something to show me. He said " I didn't want to tell you this at work but two little girls put this through the letterbox for DD". (She is 4). It is a nice looking card with DDs name on, but with a nasty note inside, signed from a name of a little girl who lives round the corner.
We have a google doorbell and can see two girls dropped it through this afternoon. The 2 girls are from our estate, aged 8 and 4. The girls are good friends with each other but lately the younger one has been playing with DD. She even came to our house last week to play briefly! When they were playing I heard little girl say 'so you known DDs name I don't want to be friends anymore' . DD didn't seem bothered and later on they seemed fine.
The handwriting is good, I don't think the 4 year old has done this.
We haven't told or shown DD on anyone else.
What to do about it? I do not know the mums well. It seems very nasty and can't believe this sort if thing happens so young now!
Tell me if I over reacting. What would you do?
