The same ways as adults do but it is illegal for a minor to have sex with someone. It's a life long commitment you will have to share with your parents most likely against their will. And money will surely be a problem since your parents are not obligated to pay for your baby. Health wise you should be fine as long as you have access to goo maternal care.
A 12 year old can baby sit
baby sitting
It's not a good idea, but in some cases it'd be possible.
Yes they can. Many 12 and 13 year olds have been pregnant and have given birth to children.
1 year old Example: If a baby is 24 months old, they are 2 because 12 +12= 24
No the age of consent is 16
12 year old girls can if they have started their periods and had sexual intercourse
That will be so nice of him!
Pap smears are not recommended for 12 year olds.
Yes. A 12 year old does not have the patience, wisdom, maturity nor means to take care of a baby on his or her own. People will think that person is selfish, stupid and/or poorly-raised. People will also feel sorry and worried for the 12 year old and the child.
The question is a little vague, but in general it's at least theoretically possible that a 12-year-old girl could have a baby, or that a 12-year-old boy could father one. The youngest person on record ever to give birth was Lina Medina, who was 5 years 7 months old at the time.
Baby sitting or dog walking.
