Ummmm ..... Next .... The fact that he only comes once a week means you only have to deal with it two more times .... Hand a notice today stating that due to a failure to provide the necessary supplies for their child and a general air of disrespect towards yourself and the day home you will no longer be providing care for xxxxx (childs name) after xxxx (date) .
And hand it directly to him and tell him what the letter is for and why.
