By you not being able to do stuff you would do when you didn't have a child like....
Now that your a mom/dad you have to take out time for the baby, change its dippers, feed it, talk to it, play with it, help it burp,change it, give it a shower and so many other things .....
Things you wouldn't be able to do would be .....
Go to party's, not get very good jobs maybe sometimes but if your young then probablys are small,if your going to school then you would have to leave the baby at home and you would be able to have sex with your partner because if you had normal birth than you just had a baby and docters recommend you not to have sex beffor 1 year or 9 months have passed but if you had Cesarean Section then docters recommend not to have sex after 1 year or 12 months but that's just some small things that affect you after you have your baby
