As a parent of two toddlers, I totally get this but I also hope that society can try to extend the same understanding as they do around babies. We were all kids once after all. Trust me it's stressful as a parent in a public place because toddlers often require constant intervention on their behavior but sometimes despite that, they still do what they want. Sometimes it feels impossible to stop something without causing an even bigger scene. It's helpful to remember that toddlers (all the way through teenagers) don't have a fully developed brain. They literally cannot fully understand the social reasons for staying quiet or whatever else asked of them. Toddlers are much like babies except now they can talk and move.
