Im a sole charge nanny and look after a nearly 3 year old and 4 and a half year old..
Given that the job is sole charge it is up to ME to decide what we eat / do etc (well thats how it works with 'my' family)
The fact is that the children very rarely watch TV with me, and NEVER more than a maximum of 1 (rarely 2) programs at a time before the TV is switeched off... On average for at least 2 days per week the telly is not switeched on at all.
During school holidays
we watch mroe telly than term time as we are home more, but i would still say not more than a MAXIMUM of 1 1/2 hours per day and that would be a rainy day!
As a qualified proffesional i would be really offended if it was in my contract that we were only allowed to watch 1 hour per day afterall i am trained to look after children and realise that watching lots of telly is not really the best thing to be doing, when we can be painting / playing games/ lego / at the park / playdough baking etc!
I would therefor NOT put it in your new nannies contract!
At interview i would mention BRIEFLY that you dont like you child watching too much telly, and maybe suggest that telly is switched off after SELECTED program is viewed (as i think that is fair to say)
also IF i had 1 hour of Tv per day i would be more inclined to 'use' that 1 hour... rather than somedays we dont have time for TV.
Equally on rainy days i would resent it and think it really should NOT be a problem to select 2 programmes in the morning, 1 while lunch cooks, another midafternoon, and another while tea cooks, which could well go over the 'hour' limit, especially if we were doing other fun activites in between!
As said befire there is no way you are realistically going to know anyway... choose a nanny who you 'bond' with and get a feel for them and what they like to do with the children...
in my opinion any nanny who regualarly lets there charges watch LOTS of TV is unproffesional. There are many more more exciting things to be doing with our time.
To be honest most of the nannies i know have the same philosophy on this as myself, so surely it cant be that hard to find a nanny who for her own reasons will not allow you child to sit in front of the telly for long periods.
Sorry this reply is so long!
