For 14 years I worked with children aged 0-8, then I took a job as a nanny with two delightful girls who are now 14 and 11 years. And I'm pregnant, soon I'll get the newborn experience too!
It wouldn't take a genius to work or all children are capable of very different things.
One thing I love about the ages of my charges is their independence. It used to be if I forgot something from the shops, I'd have to gather them all to go with me, now I can send them for me.
Another thing they can do is make the dinner. Yes, all you mothers of tots - don't lose hope. You might have needy children today but train them well and you can have kitchen assistants! Yesterday charge age 11 made vegetable rolls and I helped. This was the final result... (Masterchef, watch out).
