Transitioning to daycare

My baby is only 2.5 months old now but I was having a discussion with a lady earlier about this.

When my baby gets older I want to transition her from our in home babysitter to a daycare. I’m worried about the amount of screen time our baby sitter will allow our girl to have since I know she allows her 4 year old granddaughters to be on their tablets A LOT. I like her being there now because she is a baby and I know she gets a lot of attention.

What age do you guys think I should transition her to an actual center?
