Hello. My son is 18 months and has been at nursery for 4 months. He has not been easy, but his key worker has done an incredible job with him, and she is only an apprentice so I imagine she is paid very little, i really want to thank her. Is it ok to get her a gift voucher? probably a john lewis voucher for £30? I would also get a box of chocolates for the floor. No idea what the done thing is.
