Kelley,
hope he's not going to have potty phobia though. bbYX confirm does not like milk anymore. I held 2 bottles, 1 with water in the mag mug, the other with milk in the avent. Give him the one with milk he'll whimper then cry, give him the one with water, he'll suckle and drink. Then I pour the milk into mag mug, he still refuse to drink. Guess he's sick of milk le.
