School pick-up and after school care

Hello all,
I am looking for someone to pick up my son (4) from Alexandra primary school in wood green on Tuesdays and Wednesdays and to look after him until 5.30-6pm. I have been told that the after school club there is already full for those days - crossing my fingers that someone will drop out on those days as we are really stuck now. Both working etc. I cannot believe how hard they make it for working parents :-( if anyone knows of anyone please message we would be most grateful.
Thanks
Katie
