I dont know b4 of this ka, just learnt fm bk mamis here. but i think it is true coz when i keep giving apple to my son when he had hard poopoo, for 2-3 days, poopoo becomes very hard, so i change to other fruits instead. pear is a best choice.
reagarding 開奶茶,really not sure why yr bb will 嘔,i use to buy this fm yu-yan-sang coz i think the quality is better. as told fm my mum, she used to buy this fm a shop very many years, the man fm the shop said many of this is very 涼 & 削胃的, or u may try try 余仁生
this is also same as my boy ka, he drinks lot of water, fruits everyday and alll rice with vegtables, but still has hard poopoo, now, once i saw he has a little bit hard poopoo, will give him corn rice and "fire-dargon", keep 2 days, then poopoo will normal again, add oil ah mami
