Good resources for infant first aid/CPR?

I know good resources for baby sleep, eating, behavior... and I’ll admit it, I’d really just like having an Insta expert to consult on every conceivable topic 😂.

Anyone know a good resource or good online class for infant first aid and CPR? Really should have done it for #1, and now #2 is in the way.

(For that matter, potty training is around the corner for my first... anyone know a good potty training Insta expert who offers an online class?)

Thank you, lovely ladies!
