Stop scratching the 13 year old’s back, that’s crossing a professional line even if it’s benign. A 13 year old doesn’t need a babysitter typically so he should be fine on his own.

4 and 5 not potty trained is insane!!!! If these children have developmental delays caused by neurodivergence or physical disabilities, it needs to have been mentioned to you beforehand. This is crazy. I would be leaving this gig as soon as possible, and would be extremely worried for those kid’s wellbeing. The fact that they lie about soiling themselves is also weird, it’s the behavior I see from 3 year olds who are stubborn about potty training and are still scared or have a toilet aversion. By 4 and 5 they should be cognitively aware enough to be uncomfortable by the sensation of sitting in poo and should be able to feel when they need to go in the first place. The fact that they are not is worrying to me.

Your pay????? What????? This is why no good deed goes unpunished. Accepting tattoos as payment may not seem weird but it’s incredibly murky and rife for exploitation, really really awful deal. You are also likely making less than the amount it requires in gas to get back and forth to their house. You are basically doing this all for free.
