Just happened to my granddaughter. She is 14 months old and about 19 lbs. I can't vouch for how many, if any, she swallowed, but the bag was wet, some of the beads were on the bed, and she had a slight frown on her face. A few hours later she developed somewhat explosive, liquid stools, pale yellow in color with bb-like grannuals. They were soon followed with stomach pains and she would not eat. The doctor instructed me to give her pedialyte and no milk until her stools formed. Ingested on a Monday, her stools began forming on Friday. In total, it took about 5 days of diarrhea and weak appetite. Her breathing was never affected and neither was her sleeping, for the most part. It was a slow healing process but it never got worse than the first day.
