I was just wondering...is it possible someone else gave her a "treat" from the dinner? Were there kids around who may have innocently given her something? Maybe chocolate or pie? I would check with anyone who was at your T-day dinner just to be safe. Also, don't you have an ER Vet Hospital nearby? The closest one to me is an hour away but at least you get right in! It is worth it to help your baby and to ease your worries!
