they should be bathing seperate,i have two girls 7&8 and they shower seperate for a while now.they need to know that is their personal time,you can let him know he is a big boy and now that he is 5 he can have a little more privacy to get cleaned up.when the girls started bathing seperate that was when I let them start to shower,my older one wanted to be alone.I would help them,then I would just sit in there,but I was there if they needed. it made easy because they couldn't wait to shower they thought they were so cool.
