wow count your lucky stars, you r very lucky to have a capable and good nanny.
If you send to childcare, first of all she's still rather young. and Nursery only starts at 3yrs old.
Once she goes to childcare, you have to be prepared, are you free to keep on takign frequent childsick leave n MCs because kids at CCC often fall sick.
and the cost of medical bills + CC fees very high.. and they close latest by 7PM.. can yuo reach there by 7PM daily?
