In Episode 6 of Season 2, Dr. Carole Keim walks us through what to expect from three year olds. This can be a difficult age because children experience a lot of emotional growth and often become oppositional. Dr. Keim offers guidance on what to expect and how to handle it.

Three year olds have a lot of big feelings and drama, they often ask “why” a lot, they do the opposite of what is asked to test boundaries. They are trying to see exactly where the boundaries lie and that they’ll still be loved if they push limits. They have more refined motor skills, are more independent, and their speech has become more coherent. Dr. Keim advises on everything from behavior to nutrition and how best to handle certain patience-testing behaviors.
