>> a round of vaccines
Which and why? And how old is your son?
I have no idea which ones. There’s like 20 of them these days. It was his last round of shots. Seems like they always got 2-3 at once. He was 3 at the time and was speaking plenty of words and forming short sentences. After the switch was flipped he quit talking and didn’t talk again until he was 4 1/2. Quit making eye contact. At 4 1/2, Riding in the back of the car he started reading business signs, Commercial, Insurance, Restaurant etc. Pronounced them all correctly.
