just curious

As
My sons 8 months old. At a year they recommend whole milk by that age. Well I haven't ever given him any but he eats 3 times a day solid foods & the bottles instead of 7 at each sitting he sometimes doesn't even want the one before his nap time except maybe 1/2 oz then drinks all but 2oz of the first bottle which is normally 6oz. He drinks the whole night time bed time one which is 7oz. Anyone else's kinda doing this on their own?
