Re: DD swallowed a penny...wwyd?
My DD swallowed a penny when she was about 12 months. It got stuck, she kept gagging and vomiting but it was to far down to see or reach. She had to be put under and it had to be pulled out with a scope. So horrifying but she was fine after.
I'm sure your LO will pass it just fine, you can try to look at her poop in the toilet but I wouldnt worry about diapers
