Were going to assume that Emily and Sammy are people. You all want to know how people are born. This is a good question for a parent and we think you should ask them too. But we will give you an answer since you have been patiently waiting for IO to ask a scientist.
young scientist in room 3 has done some research and provided us with this answer. She had this to say about being born.
The baby grows in an organ called the uterus. After about 9 months, the baby is ready to be born. Labor begins. Labor is when powerful muscles push the baby out through a tube and out of the vagina. The tube is usually only 1/4 of an inch wide. Out comes the baby. You were born!
There are some books in your school library about this subject.
