Baby slack too much

Nowadays Brandon slack more and more each day. I behave exactly like those kiasu parents who keep nagging and reminding him to revise his schoolwork... do more assessments... and to pay more attention in class. *sigh... i do not know what has happened to him but his performance has turn from bad to worse. He is expertise in his arts and crafts but this is not the moment for him to relax... cutting papers and doing those lill things that he learned from the library books. In fact, I hate to scold him and punish him so often. Conclusion- no matter how much he learned from his childcare... all will be forgotten when he starts primary school!
