As a tiny piece of advice: keep earmuffs or earplugs or noise-canceling earbuds around — sometimes babies are loud, and it’s easier to stay calm and far less unpleasant with appropriate PPE on hand.
Totally true. I have definitely popped in my AirPods before dealing with a screaming little one. You can still hear them loud and clear, they don't take offense, and it's easier to remain calm in the face of their screaming.
