When I send the kids to ex, I'll be including a basic first aid kid. (panadol, nurofen, stingos etc). Just because I know he won't be prepared & I know the basics of what kids need to get by. He really doesn't
I do agree with your DH, but there are times when you just have to ensure your kids are safe. As long as the items are looked after by ex & come back from him, I would do what you're doing.
But maybe tell him its about time he bought his own & hope for the best?
