Ok so this is going to be a really bad summary because I watched it as a child and I randomly thought of it and would like to watch it again.
It's this movie about this older man and this two kids and they get trapped on an island and they spend years there the older man dies and the kids grow up and fall in love and she gets pregnant and the boy tells her she is eating too much and she is getting fat they don't know she is pregnant and she goes off when she is having contractions and at the end they make a boat and go out to sea with there then 2yr old child and I believe they try to poison themselves and this big ship finds them and it turns out that one of their dads is the captian
