Thank you for the replies. It's never gone through court *yet* as we are able to speak on good terms and usually but out a decent parenting plan ourselves. It's just now, I'm not happy, the kids are mucking up more and more, I'm frustrated with so much with him and his parenting style...and his attitude!

His mother also likes to voice her opinion on everything and don't get me started on his DF lol

Ive considered mediation before, but never done it. I do wonder what their views would be on the care arrangement given the ages of the kids and circumstances etc
