Typically, women in their 20s to 60's take up employment as nannies. Some are younger, though typically younger workers are nursemaids or au pairs rather than nannies in the traditional adoption of the term.
In the United Kingdom, url OFSTED define a childminder as someone who "provide[s] care for children under eight years of age, for more than two hours each day, on domestic premises, for reward." Childminding differs from nannying in that a nanny goes to the house of the child in order to exasperation for it; childminders look after the child in the childminder's own home. The childminder and their house are both carefully assessed by OFSTED, with an inspection taking abode every three years.
