Re: 13 month old suddenly sinking his teeth into my skin - w
My son started doing this around the time he started using sippy cups more regularly. You know the kind that are spill proof, so the baby has to bite down on it to open the valve? I am convinced that it taught him that the harder he bit down the faster the flow. I tested some of them once and was shocked at how much pressure I had to apply just to get anything out of them, it was crazy. Even when we transitioned to the sippy cups that were hard with open holes he still bit down on them leaving teeth marks, up until the time he transitioned to regular cups.
