Hi, I'm about to start with the younger sibling of one of my current mindees. The first child will need a new contract as she is starting nursery and her hours are changing. I've decided to offer a discount. Younger child full fees, older child has the discount. Do I need to have two contacts or can they go on the same one as their pay will be linked? How would you word the discount? 'When both children are in attendance, pay will be £xxx, if only one child is here then it is £xxx' or am I being daft even offering a discount?
