I would let him be a milk drinker for a mother year or two if I were you!I borrowed that phrase from you when you asked me if I had a "milk drinker" a while back. I like that phrase. There are times I wish he would be done (mostly when he cluster feeds in the middle of the night) but I would settle for night weaned. But I'm not going to force the issue since milk is the mainstay of his diet.
My youngest turned two in September and I've got another due in the spring! Yay babies!!!! 
Good morning Squatch Watchers. Here's wishing everyone a super day today!
