It is common for bed wetting and daytime incidents to occur until age 6 and can still occur beyond- development is a spectrum and different kids develop at different speeds. There’s a recommended/typical timeframe and then a timeframe that can still be considered normal. 4 year olds have just started pre-k and are not even elementary age. 5 year olds are in kindergarten. Many kids have bladder slips during this time. It is normal but is not frequent hence why it’s an incident to begin with.
As for chewing- some kids take a bit longer to understand the concept. Id go more towards age 5-6. The ability to chew with one’s mouth closed is usually solidified at age 4 which is why I see where you’re coming from but allowing a bit of grace for different factors that may be contributing to why the child is not mirroring the behavior is still important
you’re acting like people who chew loudly are the spawn of satan bro. chewing is an action that we automatically do without thinking too hard about the process, and it makes perfect sense that not everyone is aware of how it looks or sounds to others if no one actually points it out. there’s no need to shame people for a subconscious behavior that is meant to get us the nutrients to survive. if it bothers you, politely let the person know when they’re doing it bc chances are it’s unintentional
