Happy birthday to your son!(closest emoji to birthday celebration). And what a wonderful celebration for your wife and you and your family!
Have the teaching-moments conversations with him before YouTube or TikTok (or whichever social media platform is popular when he is old enough to use mom/dad's cellphone/tablet). The will pick up things from social media and online. My kids have started watching The Simpsons. I love it as it is one of my all time favorite shows. I heard my son impersonate Apu while playing on his Swtich. I quickly had him pause the game and explained that what he had just done was wrong. He had his head set while playing, so I assume it may have been a multi-player game. Had a two minute conversation where he understood that he could have insulted someone by doing that. I acknowledge that I know he didn't mean it a disrespectful way, but it may be taken disrespectfully. I have not heard impersonation from him since.
Another thing, my son loves baseball. We talk Jackie Robinson as much as Babe Ruth. I mention great people, alive or from the past, of all cultures and races even if just for two seconds, so he knows that all people are capable of doing great things.
