So glad she's okay.
When my ds was about 11 mos he started to get a really bad diaper rash around his anus. Like his poop was suddenly totally acidic but his diet hadn't changed. 2 days later, I found a penny in his diaper. Your story is way scarier -- good for your mom for figuring it out!
When your first child swallows a nickel you freak out and take them to the doctor and demand every exam and x ray in the book.
When your second child swallows a nickel you wait carefully for it to pass.
When your third child swallows a nickel you deduct it from their allowance.
In all seriousness, I am glad she's okay!! Sorry she had to go through such a traumatic experience!
My dd swallowed a safety pin one day, I about DIED! I called the doctor and spoke w/ the receptionist about it (so she could pass the message to the doc) and we laughed about my fear of her stomach muscles being super-strong and opening the pin. (I really hoped that I was being ridiculous, but I was also pretty nervous that I'd be right!) I never saw the pin in her diapers (looked for a week!) so she did end up getting an x-ray, which was clear, so she must have passed it and I didn't notice.
