Baby fever

So I'm 16 and at my brothers birthday party in June (he turned 3) I swear there were like 3 other babies there like almost new babies and I held a little baby girl and she was so cute and then last week I go shopping with my boyfriend at Carter's and I see all these baby clothes and ahh I want one but I mean I'm obviously not READY for one. Is it bad that I want a baby so badly even though I'm not even out of high school yet?
