I know some kid take 保兒加營素 & it works, but 朱古力味 is very sweet. One consultant say that some doctor doesn't suggest take this milk because the kid will not take water later.
I let my kid take it before, but she had "fai gee" in the month, so I stop it. My kid only reach the 3% of the body weight curve. But she's clever & talk very much. So, I don't worry about her too much.
Of course, I want her to be fatter, but it's not controlled by ourselves. As long as we have put the effort & tried, then it's ok.
