Medical Definition of Nerve Nerve: A bundle of fibers that uses electrical and chemical signals to transmit sensory and motor information from one body part to another. The fibrous portions of a nerve are covered by a sheath called myelin and/or a membrane called neurilemma. (Note that entries for specific nerves can be found under the names of the particular nerves. For example, the optic nerve is not under 'nerve, optic' but rather under 'optic nerve.')
My oldest two have been babysitting their younger siblings since they were 13 and 12. Before that, my friendâs daughter babysat (and she was 14 or 15). Itâs really not a big deal. They take turns watching the 3yo, and the other kids pretty much take care of themselves.
Most parents would prefer their babysitter to be at least a high-schooler, but some will accept someone 12+. 12 is generally considered an acceptable age to start babysitting. It will be hard to find people comfortable with babysitters younger than that, unless they're people who know you and/or your child personally.
