B is 18 months and has a speech delay. It seems as though when he gets frustrated and cant tell us what's wrong- he resorts to hitting. ( it started off as biting- but I bit him back one day and he stopped) I am not really sure how to deal with this. At first he was just hitting me- and I would tell him "no hitting", "gentle hands", etc. But today as I was leaving dropping him off at daycare- he hit another little girl who was all up in his face.... Is it just an age thing? Is it because he cant verbalize what's wrong.... Help. How do I stop this behavior....
