I just want to provide more info to other mothers.
When my BB's first 3 months I gave him HK 雪印 because I have special price. But after few months I read a report from Choice Magazine and the report said that HK 雪印 not only has no DHA, but also other many vitimins in HK 雪印 are under some kind of HK standard guidline. I am very regret about giving my BB this brand for the first three months. After HK 雪印, I have tried S26, A+. Finally, I choose Japan Meiji. Its DHA is higher than Sum Wing. After eating Japan Meiji, my BB's poo poo is once for two day. But after eating congee, his poo poo is every day but a little bit hard. But still okay!!!
