I don't know of anyone demanding that the ballpark be a babysitter. That would effectively be a drop-off daycare. Folks here are requesting a brief, parent shared/supervised activity other than "walking the concourse" that could help keep their kids interested in staying at the ballpark for 3+ hours. And at my local movie theater, tickets are $6-10, general admission, and the whole show is under 2 hours. Last I checked, the cheapest discounted child ticket to Kid's Appreciation Day at Target Field was $12 (limit 2) and that required a $17 adult ticket, reserved seating in the left field upper deck. (Want to go on a different day than Sunday, or sit in a different section? Kids tickets are full price, averaging $32.) All of those prices don't include fees, which I believe are around $3.50 per ticket and another $3.50 per order if you want them in advance (and remember, they are all reserved seats, so buying in advance is advantageous). Time of game was 3 hours, 11 minutes. The kid's giveaway that day was also not guaranteed ("first 10,000"), requiring fans to arrive early to ensure they got a TC Bear stocking cap. I don't really care about the costs, other to illustrate that major league baseball fans have a right to request a special "kid's area" hidden from the main seating bowl at the ballpark, as opposed to such a request at a movie theater.
