People tend to check in during these times:
Ear plugs and antibacterial hand rinse a must.
Run and hide.
Ask your older children to be careful of the little ones. I've seen too many toddlers plowed over by rough housing big kids without any words from them or their parents.
Be healthy, use the sanitizer on the left before you leave.
Padded floors, big soft stuff to play on / jump off of, and Auntie Anns Pretzels right next store. (this was formery Stevens Hospital play area)
TAKE YOUR KID'S SHOES OFF. Your precious kid is not exempt from this rule, and WILL hurt another kid if you decide you're just too special to ignore the rule.
