i didn't have any problems really with weaning my daughter off formula to milk. what i did was around the last month of 2 of formula, i would sneak a bottle of regular (or skim) milk in here and there. and she never made any faces, no reactions, just drank it. and then once all the formula i had was gone (she was about 14-15 months old) i gave her regular milk. right now i switch her back and forth between whole and skim milk. her dr said is all has to do with the amount of fat intake she gets. so when i know she's eating something fatty (like mcdonalds nuggets when we're out much longer then planned and that's our only choice) i won't give her anything but skim milk. but if she's not eating that much fat, i give her whole milk. but please, watch out how much milk she's drinking. the dr's told me around 12-18 months they should drink 18-24 oz of milk, NO MORE then that. well, my daughter was drinking 24-40 oz of milk a day, so i started watering down her milk (regardless of whether it's whole or skim) and she doesn't seem to care about that either. giving more then the recommended amount of milk can hurt your child in the end. i was big on milk as a child, and now i'm anemic, and my daughter's iron levels were low too, but once i started cutting the milk with water, her levels went to PERFECT. it's still an early age, but don't make it a habit of too much milk (if she even drinks alot). well, hopefully you find your way of weaning. but it should be easy, just throw some regular milk in here and there the last month or 2. and please, keep her on the formula until at least 12 months...they don't get as many vitamins in whole milk as they do in formula.
