There is a mom on a playground that we go. She has two sons aged 3 and 1, and whether i am with my children or just go by, i see her children fall, bump their heads, fall off the slide. Now i know this happens to kids, i have 3 of those, but i see it happening every time. She runs home and always blaming someone that they left a glass, so her child cut her finger, somebody left the gate open, so her children run out. Now when i see her or her children on a playground, i take my kids somewhere else. Have you noticed someone like that on your playground. What you do about it?
