I've known about the Poison Control Center for many years (I'm an RN and used to be a Paramedic many yrs ago) but never thought I would ever need to call them for myself.....
When my oldest son as a toddler, he got into my FIL's Contact and chewed a bunch of the capsules open...I called the PCC and they were very helpful and kind. Even with all my experiance, it scared the bajeepers out of me--that was MY kid!! They talked me though everything and then called back several hours later to check on him. THEN, they called back again a few days later just to do a final check.
Thankfully, he must not have actually swallowed any of the tiny pellets inside and had no ill effects at all, but I really appreciated the PCC's help.
Don't ever hesitate to call them if there is ANY chance someone has gotten into something they shouldn't have. They are a great bunch of folks......
