Two kids at 19? Good or bad idea.

Hey I just turned 19 & I have a 1 yr old (soon to be 2 in July). Me & my sons dad have been broken up since before my son was born and now I have a new boyfriend. He's so good to me and my son, but he has no children. He wants one though, and not in the future but NOW. I've been having baby fever lately and kind of want to give him one. He told me if I wasn't ready we could wait bc he loves my son and look at him like he's his. I really don't know what to do. I know we can make it work but I hate the thought of being judged for having another kid so soon. What are you guys opinion?
