For those of you mommies out there I just want to know how hard is it to take care of a baby if you don't wanna answer it then don't read it

 My boyfriend just told me he wants to have a baby and he's ready. He never had a father figure in his life an he has always wanted to be a dad and I really do love him. But with me I don't think I'm ready. Yes were both stable, have our own jobs, cars, but we don't live together and I don't think that's enough to handle a human being. He's 3 years older then me I'm 20 he's 23. Sometimes I do wanna be a mom and sometimes I don't I do feel like being one sometimes because I know pregnancy is a blessing but I don't know about the back pain, giving birth, and stuff like that lol. Also finding out the gender, seeing your little one for the first time on  ultrasound, you own baby shower, the kicks, etc yes it's a wonderful feeling and babies are adorable and a blessing butttt knowing their not going to be a baby forever that's your whole life right there and yes my boyfriend and I would make wonderful parents one day and he's not forcing me to have one right now I talked to him ahout it already and he understood I just want to know how your whole life changed when your child first came to the world and if you now have more then 1 kid already how was it dealing with your first born. Also if you have twins cause you never know in the long run I can get pregnant with twins. I'll wait a few more years and I know motherhood will come one day for me. Thanks ladies I would love to know
