Thank you for bringing up this important issue! I often take children to parks in both boro park and flatbush and i see this happening all the time. The examples you give are exactly whats going on, and its really really sad. So many times i see toddlers running around with zero supervision, sometimes i wonder if they just took a stroll to the park by themselves. What irks me the most is when the babysitters strap the kids in the swings and push them for an HOUR while they enjoy shmoozing. No kid wants to be shaken up for a full hour. But hey, it works for the babysitter -she doesn’t have to run around.
Parents, its your your kids we’re talking about. Do Something!
