Weaning

Trying to get Henry to stop nursing has been a challenge. I am not sure of how to do this. I am thinking the Nursing is more of a comfort for him then a need. He can eat everything and he does but he still refuses to drink Milk or anything else beside water out of his sippy cup. He will drink some juices if it is out of a big persons glass. Any Suggestions would be appreciated. I am thinking of just cutting him off except for naps and bedtime for now. I figure he will learn not to depent on me that way. I don't know does that seem mean? Well the joys of Motherhood. I love them but sometimes it is hard.
