As used in section 13(a)(15) of the Act, the term babysitting
services shall mean the custodial care and protection, during any part
of the 24-hour day, of infants or children in or about the private home
in which the infants or young children reside. The term ``babysitting
services'' does not include services relating to the care and protection
of infants or children which are performed by trained personnel, such as
registered, vocational, or practical nurses. While such trained
personnel do not qualify as babysitters, this fact does not remove them
from the category of a covered domestic service employee when employed
in or about a private household.
