There is currently an outbreak of measles in London and this illness should not be underestimated.
Measles is a highly infectious viral illness that can be extremely unpleasant and sometimes leads to serious complications. Measles can affect any age group but is most common in young children, although this outbreak appears to be hitting our teenagers particularly hard as many teenagers were not vaccinated as babies. You are never too old to get vaccinated!
People can be prosecuted for neglect if they leave children on their own and something goes wrong. This is a highly contentious issue and one that becomes even more complicated when contemplating when a child is old enough to be left in charge of other children and babysit.
Rospa and the NSPCC both have published guidance as to when a child is considered ready to babysit, their advice can be found here: http://www.firstaidforlife.org.uk/rospa-advice-on-when-a-child-is-old-enough-to-babysit/
