Hi My DS is starting Holland park school in September 2019, I am trying to reach out to other parents and children that might be starting HP in September - as my son only knows one other person attending the school so it would be good to organize a playdate or get together etc - please let me know if you would be interested thanks
Why on earth would it be awkward? What a weird comment. There must be tons of children starting at Holland Park this September who don't know many others and would love to get to know a few more before the autumn. 11 is still a child.
I suggest NextDoor where you could create a post asking for others to get in touch, or Mumsnet Local in the appropriate area.
