I have a 30 month old son and sometimes he showers with me. Not often but kinda rare. If not he walks in on me since I leave the door unlocked because in the mornings it's just me and him home. Is this OK or I shouldn't be doing this at all since he is a boy. On another note, my 5 y/o sometimes showers with me but it is rare. Should I stop?? If your children do shower with you, what is the maximum age to stop??
