Reliable, my children love her.
Annabel has worked with my 2 girls (now 10 & 7) since last summer. It was a difficult time when she started working with us, as my wife was terminally ill. Despite the tricky situation she immediately formed a good rapport with my children, and helped look after them during tricky circumstances.
She has done 'normal' babysitting, as well as taking the girls out for trips and activities.
I trust her implicitly. My girls adore her, and often ask me when Annabel is next 'visiting'
I would estimate that she has looked after the girls for whole days about 20 times, and has babysat on evenings for us on at least another 50 occasions.
