I would suggest getting an appointment with a social worker or a child therapist. A therapist might be the better option to start with as I think they will be able to get a better picture from your child as to what is going on. There's a huge difference in using spanking once in a while for times when a child is deliberately disobeying while knowing the consequences, and using spanking out of anger and frustration or over every little thing. I can understand being worried especially if there were already anger issues involved. I've been spanked and I honestly think my dad did the right thing in those situations, and I hold no resentment to him for it. I think a therapist would be better equipped to form an unbiased opinion. Plus if they do think the spanking is becoming abusive, you will have their backing when talking to a social worker and have someone else to verify what your child is telling you, so it's obvious you arn't the one making things up. Obviously I don't believe you are, and I doubt your child is making it up either.
