Is it okay to take a shower with 12 year old when you are 15?

It is not appropriate for a 15-year-old to shower with a 12-year-old. Children of different ages have different needs and levels of privacy, and it is important to respect those differences. It is also important to consider the safety and well-being of both children. Showering together could lead to physical or emotional discomfort, and it could also create a situation where one child feels pressured or violated. It is best to avoid any situation that could put either child at risk.
