Every year after report time I buy my children a hardback book. In it I write that I am so proud that they have worked hard this year and tried their best. I was accused, by one mum, of bribing them. Personally I think that I am rewarding them for their effort, not the result. I can't know that they have tried their best until I read the report.
Give her the treat. Tell her that you are proud of her. After all, lots of people at work get bonuses if their appraisals are good.
you said you are going to give her a treat for 'getting through her 1st year', but you make specific points like she has worked very hard to fit in and make friends - they are happy with her etc, i think on those points she really deserves a treat - tell her she should be proud of herself, and she will be delighted! go for it!
Oh, give her a treat, the little love. My parents quite explicitly never linked treats/rewards to academic success, and I cannot say they have terrifically good parenting skills. I think she's made a huge effort, she's really worked at being in a group, which is difficult, and I reckon a trip out would be well in order. Cinema, perchance?
what about printing off a 'best little girl in the world' certificate or something so she can pin it to her wall and then she has a constant reminder of how proud you are? ds1 really responds to stuff like that. and give her a lovely treat too of course.
I was just asking my DH the same thing. He said treat too!
The book sounds a lovely idea and something she will cherish for a lifetime. I'd let her choose something cheap and cheerful too though as she's now expecting a treat and perhaps a hardback book, beautiful as it is, would not be a 5yr old's idea of exciting.
