I weaned my son at 11 months, I was about 6-8 wks pregnant so I really did not want to nurse him anymore. I don't know if I am giving you advice, but this was my experience. My pediatrician said milk, unlike formula or breastmilk, is not his primary food source that he needs lots of nutrients from food, but of course calcium was important but that could come from cheese, yogurt, etc. Since he was used to the sweetness of breastmilk (oh I was nursing him 3 times a day)I made him a 6-8oz bottle, give him just a little at first though, and would put a lil' cereal and splenda and he would drink it all. He did not eat much at all though with all this milk so I am now giving him 4oz bottles three times a day(one bottle before his two naps and at bedtime), I don't use splenda anymore, he uses a sippy cup well so I am trying to start milk in sippy cups too. My doc said splenda is safe but not other sweeteners but your son might not even need that. I would look up how much milk he needs I can't remember the exact amount that I found, but milk is pretty fattening and gets the body used to animal proteins, basically kids don't need to chug it all day but need lots of water, fruits, and veggies, this is from what my doc said and I read. I was surprised that at one he really doesn't need that much for his little body. Good luck!
