I only have full-time and part-time rates as well (though I don't generally take part-time anymore). Part-time rates are usually a bit higher daily rate than full-time rates. Also, I have not heard of home daycares charging different rates for different ages. If they are full-time it is one rate if they are before and after school it is another. I don't think there is actually that much difference in the care needs of a 12 month old and a 2 year old for example. The 12 month old has more physical needs like diaper changing, being fed, being held, etc. But the 2 year old has more behavioural, educational needs. A 3 year old will need more educational activities, school-readiness prep etc. I don't find one age more work than the other. And by the time they get a bit easier, they head off to school...LOL.
