I was smacked as a child and I am of the view that it hasn't done me any harm. Before I had kids I was certain I wouldn't smack. When I had dd1 (5) I didn't smack her (PFB and all that) but I think if I had she would be more disciplined now. Hindsight and all that.
With dd2 (19 months) I wasn't going to smack either but now she's into toddlerdom and getting up to all sorts I find it's the only way I can stop her doing things. I nly lightly tap her on the bum a couple of times and she is wearing a nappy so won't really hurt. But the shock of it stops her being naughty. I do give her a warning before I do it. I tell her no but she just laughs and does it again. I have a 3 strike rule. With dd1 because I've never smacked her I don't intend to start now. I can reason with her and punish her with taking away things which is hard to do with a 19 month old. I intend to stop smacking dd2 when she reaches an age she'll understand punishment.
I don't really want to smack them both as they get older but I won't rule it out if they're terribly naughty.
What are your views? And how do you discipline your DC?
