Babies can't be born with teeth. We don't really know why, but it is simply so. babies start to grow them at the age of 1-2.

"Probably teeth" ^ this is wrong. Babies start to get their teeth before they even turn 1 year old, and its not that they are born with out their teeth. Their teeth are in their gums but haven't yet pushed their way out. I believe this person is referring to the fact that some people think that babies are born without knee caps and don't get them until around that age. This is wrong as well. Babies are born with knee caps, however they haven't ossified yet. A baby's kneecaps start off as cartilage and eventually ossify, becoming bone.
Not all babies get their bottom teeth first. However, the bottom teeth generally start to appear at around 6-7 months.
