As I’m sure you know, Danielle, this custom is ages old. I don’t believe that there is anything wrong with teaching your child to eat with only one hand. But at 14 months, the fact that he eats so well is a blessing, so I would hold off on the training for a little bit.
One of the benefits of single-handed eating is that it forces us to slow down and probably helps with weight control. Still, your child sounds happy and well adjusted and I see no reason for you to be adamant that he use his right hand only. But he must be taught proper hygiene at an early age, especially frequent hand-washing. Please discuss this with your husband, as this custom is also strongly cultural. If he agrees, begin immediately to teach your son to wash his hands before each meal, making a nice, soapy lather and singing the “ABC” song from beginning to end before rinsing.
Congratulations on being such a concerned parent and having such a wonderful little boy!
