I have an almost 3 yr old who is still on formula, and I mean high volumes like you'd feed an infant. The child weighs more than my kids did at 4.5 yrs and eats everything I serve. There is no allergy issue either. My fees are tiered, so as they age, my fees reduce. The child is now at the cheapest fee bracket. The problem is the parents still expect me to measure/mix this formula, and quite frankly, I don't feel I should have to do this at this age. Would it be rude to tell them to prepare it themselves?
Can I ask them to phase out the formula, and go with water or milk? I've never seen anything like this before...
