See, this is why we are all different and have to do what is best for us no matter what advice we receive from others. My schedule is quite different from your schedule. But if you and your family are eating breakfast really early in the morning and this child is arriving at 8:30 I would definitely tell the Mom that the child should be fed before arriving or he will have to wait until morning snacktime as per your schedule. I would not be changing my routine for one specific family.

Remember that you will be adding more families eventually as you grow and your rules are the only rules. Do you really want a child sitting and eating, even food brought from home, at 8:30am? Will that interfere or annoy you when you have several other children in care and your schedule says 'freeplay'? Just thinking ahead for you. Believe me, I've learned the hard way that if you let a family have special treatment they will push you on more and more and more as you go along. Best to be tough from day one.
