"Well sorry none of you agree with my sticker chart for remaining at the tale during a family dinner and eating the food on her plate. Also about loosing stickers for bad behaviour."
As others have said, rewarding her for eating everything on her plate is not a good idea. It teaches her to over-ride her full feeling, which can cause problems when she's older if she doesn't know when to stop.
I don't like the sticker chart idea in the first place but really can't see the logic behind removing stickers you earned. A bit like your boss at work taking part of your wage off you because he didn't like your work in the last hour of the week.
"We have been working this way since she turned 4 and it has improved her behaviour greatly."
Short term maybe. But I think you might be storing up problems for later.
"However I fail to see how I could have said - naughty girl for ruining a whole carpet - you know (and she does know) nail varnish doesnt come out. Then take her down stairs and hand over a £5 note!"
While I'm sure she does know, sometimes with young children they have to be constantly reminded until they get older and understand more.
I don't think anybody is saying that immediately after pointing out that nailvarnish on the carpet wasn't a good idea you should give her £5. The £5 was for her stickers, surely, and could have been given at a later time.
Serendipity hit the nail on the head, with the fact the punishment seemed to have no initial impact.
I think tinkerbelle's mum answered that one. You don't have to reduce a child to tears for them to understand that they had done something you didn't like.
And DD had only gone after it as we had been at friends during the afternoon, who's 6yr old DD has play make up - which I personally dont agree with, and it had reminded her that mummy has some.
Well there you are, then. Possibly all other thoughts left her head and she just made the connection with the play make-up and your nailvarnish.
I feel confident in my DD's ability to understand her punishment and she is a lovely caring little girl. So I am not about to change something that works for us.
I do think that it might be worth you having a read through
Unconditional Parenting by Alfie Kohn.
I'm trying to be helpful here as you might find some ideas in the book which you might find better for you and your dd in the long-term.
