Good Lord, that would have been terrible scary. Thankful she's okay. I tell ya what...this isn't as bad but still freaky, speaking of sticking things where they don't belong. When my son was two, he proceeded to stick a rock up his nose at daycare, they couldn't get it out. I drove all the way to hospital totally freaking because I just knew he was going to breath it back into his windpipe and choke. we got there & they managed to get him to blow it out of his nose. Phew...then about 6 mos later..I caught him getting in the silverware drawer at home, I asked what he was doing, he says "I got a nut up my nose"! WHAAAA, yep stuck a peanut up his nose. He was trying to get a spoon, I guess he thought he was going to dig it out! This time they had to use a cathader and shove it up his nose past the nut and inflated then pulled it out. He was not happy about that procedure and needless to say after that, he never put anything else up there. All I'm saying is stuff like that can happen to anyone, no matter how close you watch them, kids get into stuff and you have no clue. I'm sure that the last thing you were thinking is that she was going to shove a marble in her mouth. Take it easy on yourself, not your fault. You obviously reacted the right way and handled the situation. You did awesome!
