Peaceful co-parenting after divorce isn't easy, but this dad says it's worth it.  Just because you're divorced doesn't mean you can stop being nice to one another.

Billy tells us about how he woke up early to buy flowers, cards and breakfast ingredients so his kids could surprise their mom, his ex-wife, on her birthday.

'As usual, someone asked me why I still do things for her all the time,' Billy wrote.

'This annoys me. So I'm going to break it down for you all.  I'm raising two little men. The example I set for how I treat their mom is going to significantly shape how they see and treat women and affect their perception of relationships.'

His point is that divorced parents shouldn't let negative feelings about each other lead to petty behaviour in front of the kids.

'Kids want to take care of their parents, and they can't do it alone. So if it's Mother's Day and the kid doesn't have anything to give to his mom...that doesn't feel good'.

It's a two-way street: On Father's Day, Billy's ex-wife makes sure their sons, ages 4 and 8, have a  present for him, too.
