Swetheart, we have all heard horror stories about the abuses and overzealousness of Child Protective Services, but what you wrote was simply horrifying: Face slapping a four month old? Dropping her instead of sitting her down? Signs of previous fractures?
We have all also heard that love can be blind, and I believe that such blindness is causing you to overlook what is happening to your precious baby. I pray that you listen to Luella, because what you have described just does not add up to a mere series of accidents.
