Your solicitor ageeed to write a letter about this? Presumably in that case it’s causing problems at school, as otherwise you’ve not got any basis to complain. Is it that sort of unnatural white blonde that turns up in Daily Mail school stories every now and then?
I am unlucky enough to have a very pushy, slightly unhinged OW in my life. She keeps bleaching my 10 year old sons hair even though I have told my ex (both directly and via a solicitor) that she does not have my permission to do this and must stop.
It is infruriating that both my ex and her completely ignore my wishes with regards to my son. What can I do to stop this behaviour??
