As a single mum to four unruly children under the age of three, Rosie Parsons's situation is an extreme test for The Three Day Nanny. Two and a half year old triplets Summer, Sienna and Jacob were an IVF miracle and when 13 month old Zach came along Rosie thought she had the perfect family. But then her marriage broke down and she was left to cope alone with four extremely demanding children who fight for their Mum's attention. At home they hit and bite and often trash the house as they battle for attention, but it's the quiet triplet that usually wins - with her extreme clinginess and constant demands to be carried she leaves Mum with no hands free to tackle the naughty behaviour of the others.
