Bose QuietComfort 35 with white noise playing on them should block anyone not yelling right at you. Bought mine used after some extensive research, but maybe there's something better nowadays. If you added foam earplugs and music to that you'd be deaf.
Idk about AirPods in particular, but you could try layering good PNC earmuffs over your ANC earbuds? I doubt you'll get it <10%, but should still help cut a lot of the high-frequency crying.
They block about 50% of the noise of a crying child in the area. Not nearly enough.
