I'm a piano teacher and will return to work when my ds is 4 months old. Many mums of my students saying they would love to look after my ds while I teach their children. I'm keen to take up their offer but at the same time thinking: shall I reduce the tuition fee? As a mum do you think that is appropriate? Or would I insult them? If I was to reduce tuition fee, how much do you think is appropriate? £5 per hour?
