often times boats and water are common dreams for those who have suffered abuse or are currently dealing with some sort of abuse. Like living in a bad relationship, or working threw past abuse currently. The not knowing which child to save is symbolic of not knowing what part of you to save. It really doesn't have to do with your children but more how to save yourself. It is a dream accompanied by confusion an inability to choose. There is not correct answer and the choice is going to hurt you or someone you love either way.

I don't always get dreams right, but does this sound like a correct analysis to you. Not knowing your past history and the events leading up to this dream it makes it kinda hard to say. This is a very generic interpretation.
