I don't know if this goes here, but my 1 year old likes to spit liquids out and let it roll down his chin. It is driving me crazy, because it is a mess and waste. He now does this with his milk, water, and this morning his medicine. As soon as he starts doing it with his milk, I take it from him. It is too expensive to have him just spit it all. With his medicine, now I am concerned that he isn't getting the proper dose. Is there a way to teach him not to do it? I just take it and tell him no.
