I want a baby.. Is this normal?

okay, I am 13..... no yelling at me!!! lol I know I am wayy too young to have a baby.. and I have ni intention too. But when I see like pregnant 16 yr olds on like 16 and pregnant (an MTV show) I just get jealous cause I want a baby not snuggle close to me. idk y but babies like me. my bffs sister is 2 and cries when i leave her and she always wants to see me. babies always grow attached to me and i just really want one. again, no intention of having one!!! lol. is this normal? y do i feel this way?
