We're not changing anything today. Just watch. When does your kid reach for a screen first? What's happening right before that moment? Drop it in the comments.
My 4 year old tends to ask for tv time right after breakfast throughout the week. She usually tries to play with some toys or something and you can watch the boredum creep in. or the other thing I have noticed is she will see us working (since we work from home) and ask if she can watch tv while we work.
