First of all, I think your way too young to have a baby.
My mum and my older sister fell pregnant at sixteen and it was very very hard on them. They didn't stay in their relationships with their boyfriends, so basically they had to raise their baby without the father.
I only just turned seventeen and trust me I went through a stage of wanting to have a baby too, but from what my mother has taught me about her experiences made me learn that I'm way too young to handle raising a child, it wouldn't be fair on the baby.
I think you should wait until further on down the track you settle down with a good partner and then discuss raising a child together.
