Hello, eight days ago i dropped a pyrex dish on the tile floor. i cleaned it very well. i have a 3 yr old grandaughter and a 15 month old grandson. today saturday i get a call from my daughter saying that the kids have "glass slivers" in their feet, the feet in areas are red, also painful. now, approximately 9 days ago i called my daughter at work and told her the playroom was full of ants, small ants. i even saw one on my grandson. now, checking the web i feel that if it were glass slivers from eight days ago would there no be a sign of any blood, with multiple sites on of red on her feet, only to come to be very painful & red yesterday, or ant bites? i checked the web, read my tabers book, all gear towards ant bites. please let me know what u think of this situation. PLEASE..marjorie
