Is the WT against that? Well they may say if questioned that - no we are not saying to hit your kids - maybe, but look at the scripture they use to defend their stance on discipline. Prov 23:13
Official WT doctrine:
A rod is a symbol of authority. At Proverbs 13:24, it refers to parental authority. In this context, employing the rod of discipline does not necessarily mean spanking a child. Rather, it represents the means of correction, whatever form it may take. In one case, a rebuke kindly given to a child may be sufficient to correct improper behavior. Another child may require a stronger reproof. “A rebuke works deeper in one having understanding than striking a stupid one a hundred times,” says Proverbs 17:10.

Personally I hope - that every JW knows this official position - for the benefit of children.
