Trustworthy afterschool nanny London

I have been an afterschool nanny for 4 years with 2 kids ages 5-6 back then. I pick them up in school and bring them to their afterschool activities. i help with their homework and cook food for them be with the kids until parents comes back. I can also do housekeeping on the side if there is time. Babysitting is okay aswell. I can give reference if needed.
