I'm not a mommy, but I know infant and adult .c.p.r. I'm red cross certified in first aid, cpr, heimlich maneuver, and babysitting.
i was babysitting a 4yo once who started choking on a hot dog her parents gave her before they even left. her mom freaked out (understandably) and i did the heimlich and thank god she's okay. her parents decided not to go out after all, but i got paid what i would have gotten for sitting because i kept my cool.
i would .H.A.T.E for something major to happen where i'd really need all of my certs, but at least i'm prepared.
