My advice is for outside of school. My wife and I are pretty introverted. Don’t really want that for our kids, doesn’t mean it won’t though. My wife was bullied quite a bit growing up, myself not as much. What we try and do for our kids is give be them as much positive interactions with others as possible in multiple situations. I have a 6 year old in kindergarten and a 3 year old. I make both of my kids do the interaction around town like ordering at a restaurant so they gain confidence in speaking for themselves. It has done wonders for the 3 year old who was late talker. We rehearse what they are going to say so no surprises. Most find it cute. We also belong to a church small group so they see us interacting positively with others. Doesn’t have to be church just somewhere they see us interacting on a regular basis.
One other thing we do is make our kids responsible for things at home. They do quite a few chores that are age appropriate. I think it proves they are capable and builds confidence. I don’t let them get away with not doing something they can do for themselves. It is a process but we slowly add to their skills. Folding clothes, setting the table and clearing it afterward, and tying their shoe. Takes time but it is great time saver when they get the hang of it. Make your own sammich, get your own snack.
The 6 year old we waited a year before starting school. Hopefully he will be one of the older more mature kids in his class. So he is the one setting the example vs learning bad habits from others. He also did transitional kindergarten. Small class size was great. There were a few behavioral kids in the class but the teacher spent a lot of time on emotional intelligence. So he a plenty of practice dealing with situations and the teacher had the class size to do it. The TK program was great but our school district is wanting to get rid of it. I don’t think they really promote it either or utilize it.
I would like my kids to do martial arts because they are both on the small side. Sounds bad but I think there is confidence in walking in a room and knowing you can kick someone‘s ass. Just not ready for the time commitment. I want them to learn to swim first.
