Everybody has to cross the river

Excuse me, it was Timur who had a parent crossing with a child of the opposite gender. That is what i meant by assumption. The condition don't excuse a parent crossing with a child of the opposite gender.

I reject my previous assertion. The problem can't be solved if the number of sons or daughters exceed the number two, under the given conditions. I suppose, the problem corners your to work with two sons and two daughters.

Ice Demon is right about his solution.

I actually found out this visual game on the internet and the only solution that worked is Ice Demon's.

How wide is the river? Are there strong cross currents?
