1. talk positively, for example, don't say: stop climbing, say: stay right there
他讲着讲着，突然说：now that we are talking, don't think of blue, anything that is blue，我follow着他，脑子里突然就出现了海啊，天啊，想着，别想这些
然后他说，what is in your mind? i know the answer, and you know it too. I believe you have something blue in your mind。。。
他一下就打动我了，是啊，我还想着要听他的，还是不断在想blue，乐乐听到我说别看电视的时候，不是更想看了？
2. don't yell, raise your voice only when you have to
3. enter the little one's world first. For example, when she is watching TV, and you want to ask her to go sit for dinner. don't say: turn of the tv, go to you high chair, say: honey, is the TV you are watching wonderful? she will most likely say, yes. then, you ask for the names of the main character, she will most likely reply. and then, ask for turning off the TV and going for dinner

these all sound very easy and obvious, but when pointed out, i think it is reasonable, and it reminds me to do it...
