Babysitter and 3 month old tv

So I rarely let my three month old son watch tv.

He started at the babysitter this past week and everyday if went to pick him up he's proppes up in front of yhr damn t.v.. I know o know first time mom worries.

I just dont think its good.

Now my son will whine of he wants to watch t.v.. I will try all soothing I can think of...turn on the tv and he's happy again.

I just didn't think she wouldn't prop him up in front of their giant 60 " tv...

Any advice on how to handle this
