I see it all the time on buses. Pushchair facing the front and the mother behind, fixed on the phone.
Less than half of them put the chair facing back, which is the correct way in case of a sudden stop. And it affords eye contact parent & child.

As a non parent, I once read that engaging in what the child is interested in allows them to learn faster. Ignoring or deflecting them with other things, doesn't. When in the company of a toddler I tend to follow their interest, now.

Some understand, some don't. As Winston Churchill said "The two most important jobs in life are given to amateurs, parenthood & citizenship"
