Just because this place was an office where kids go for lessons doesn't make it ok for kids to act like screaming maniacs. My pediatricians office had to put up signs asking parents to keep their children from running and climbing. At the Children's hospital my DD's specialists are at, there is a floor of just all the specialists offices. It is a great welcoming place with many different hands on activities, cool fish tanks, ect, but it is still a dr's office and I have, more than once, seen an employee ask parents to please stop their child from running, screaming, climbing. I also saw a parent take offense to this and SHOUT "This is a Children's place and they should be allowed to act like chiiiiiiiildreeeeeeeeennnnnnnn!!" The nurse said it is a hospital and walked away. I bet those mom's in the OP's story think everyone, just everyone is a child hater because they just don't understand how special their children are and how they neeeed to express themselves !
