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.
Basically, if your child is age seven or younger, they should never be left alone. Kids ages 8-10 can be alone briefly, and ages 10-13 for longer periods, provided there is back-up supervision. Babysitters should be at least 12-13 years old, and can babysit for longer periods as they grow older. Get recommendations from friends. 2  Trade childcare with friends who have kids. 3  Do not hire a sitter under age 12. 4  Watch your childâs reaction when you tell them a sitter they know is coming, and listen to what your child says about the sitter afterward.
