Three strikes and you're out?

How many calls can you make to Poison Control before they send out Child Protective Services? Anyone know?

To date we've called three times:

1. LW drinks EM's trumpet valve oil. Poison Control says to watch for signs of a cold, as sometimes kids aspirate some of the liquid and it can lead to pneumonia. LW is fine. (LW actuall drank the valve oil a second time--opening the bedroom door, the closet door, and the trumpet case to reach it--but we didn't call the second time because we knew the drill.)
2. Two weeks ago, LW eats diaper rash creme (the Wal-Mart brand). Our call to Poison Control is the third call within a half hour for the same thing. You'll be glad to know diaper rash creme is not toxic. (Must not come from China.)
3. This morning, LW opens a bottle of Extra-Strength Tylenol and chews up and spits out one tablet. "Gum," he said, but it was more bitter than he expected. For future reference, a child his size can consume four 500 mg tablets "safely." Why do I think I might need to know that in the future? (Oh, and just a warning. They make Tylenol bottles without child-proof lids. It does say, "Not for homes with young children" but somehow I missed that when I was staring at the bizillion varieties of Tylenol on the store shelves. And somehow it didn't even register that the bottle was easy to open. We have since thrown the bottle out.)

Sigh. Will this child survive his childhood? Will I?
