Dear moms! Can you advise me on how to handle a child who is 2 years and 5 months old and absolutely refuses to wear a jacket or hat? It's cold outside, but he's lying on the ground, on the cold asphalt ? and he got sick because he took off his jacket right on the street! I offer him a hat with ties and without, and two jackets for choice, but this person won't budge an inch. He cried all the way home yesterday because he wanted to take off his jacket in the car, which was not allowed.
