I agree that you should both agree with one parenting style, and smacking is not okay with me either. My husband and I have never hit our child and fortunately we both have a similar mindset when it comes to parenting. I wish you well with this issue.

It would be really helpful to your family in the long run if you could get this worked out sooner than later. A counsellor could help you both come to an agreement and see each other’s perspective.
These decisive issues sound small now, but when they get to teenage age you need to be on the same page. You’ll need each other for support and you will need to be able to trust that your partner’s parenting is at least compatible with yours. Investing in this now will, hopefully, save headaches later.

We are starting with warning and if not working then light smack in hand or bum.
