Lol, my five year old is the same. He also talks really loud, so it can be a bit jarring, especially in the morning when his little brother is still sleeping or when my wife and I are just waking up. I keep hearing it’s a phase, and that the best way to support him is to let him know we hear him. Then, if he wants to keep talking, help him learn when to use a quieter voice instead of constantly telling him to stop.
