I was talking about this with my OH the other day. He was raised with the occasional smack I never was.
We've agreed to raise our kids without smacking... I think in a few years time people might look back on smacking as a bit cruel...
Whatever this "study" appears to show,if you teach your child do as I want you to or I'll hit you,they'll go away and do the same.If you talk to them and teach them to reason,they learn how to behave rather than comply out of fear.Aren't we teaching them self discipline for their future.This isn't new gems of information we must rush out and research,we all know all this already.
There are people who need to learn parenting skills,discipline being one of them.If you lash out at your child you teach them nothing,but I do know of parents/homes where it is the ultimate sanction,where all else fails.In most cases it's not about abuse,more parents do it the only way they know how.In most cases people are trying their best and actually doing a good job.
We don't need a "professional" to tell us how to raise our kids,there are many ways to do that.There's only one professional that matters in my house,and that's me,cos I'm Mummy,I am the law,and I don't need a dozen recommended reads to tell me how.
