DS is almost 13mo, I still nurse 2x a day but he gets cow milk (sometimes mixed with BM) the rest of the time. He gets it in a straw cup, which he knows how to use very well! But lately, he's been refusing it. He either won't take it at all or he'll drink a little bit and then shake his head or just push it away; sometimes he'll drink it and then dribble it out. I am thinking it's a stage and in a week or 2 he'll start drinking it again. He's eating well. Any other thoughts? I hope I'm right!!
