It is notable that the examples of Harry's accidental magic given in SS include one event where Petunia was the only other person around -- when the ugly sweater shrank to doll-sized. Petunia "decided" that it must have shrunk in the wash; she of all people knew better. This supports the idea that she didn't really support the idea of squashing the magic out of him; she may have thought ignoring it was a better idea (and she was right in many ways).
