My son did the same thing. He rarely had a bottle but would take one without a problem until he hit 3 months. Then refused to take it all the sudden. After some research here it what I found, have your husband try and give him the bottle, or someone beside you because he most likely won't take if form you as he can smell your milk. In fact you shouldn't be in the room or around when someone trys to give the bottle, also have them face baby out and in a sitting position. They recommend making it different from breastfeeding positions. Also try the bottle before he is hungry. Good luck, it sometimes worked for us, we didn't push it too hard and now he is 5 months and started taking a bottle again all of a sudden, even from me.
