Mate if you get bored playing pop songs, it’s not the job for you. I am a former drum teacher, and 90% of the students only remained at a basic rock beat level, because they either don’t have drums at home or that they won’t practice. Prepare yourself for lots of monotone hours playing same grooves and same songs. Look for some very easy songs and make a playlist, so you can cycle them.
The dealing with the children part is the easy part in 1 on 1, as opposed to in school. Just treat them like you would treat an adult, but be a bit gentler and softer. Because you are a Woman, you will automatically be less menacing. Just take it easy and talk to them.
