How do you shower?

Hello I am a single mother of 2 boys, my mom has been living with me for about 2 years now so I have had a lot of help with my boys. However I’ll be moving on my own again in September and I need to know how do you shower with two toddlers. My youngest is 2 and my oldest is autistic and he is 3. I know I can wait until my 2 year old goes to sleep but my 3 year old is very dependent on me. For the most part he cannot go to sleep by himself, so he sleeps in my bed. I am just trying to figure out how this will work
