My fav age of kids is 18 months. They are in this cute stage, can understand most of what you say, start to communicate and can find enjoyment in everything. Love 18 month olds before they hit the 2s and 3s. The 2s are still okay 2 but 3s is touch and go because they get into this mode where they want to be totally independent but yet they aren't developmentally ready to make all their own decisions or do everything themselves so it leads to frustration and tears and no one is happy.
