香蕉好涼, don't give it to him lah.... How long does your son - did not stool? or stooling hard one??
If you are breast feeding, suppose he would not like this. You should doing massage for his tummy. Also, if he take around 26 - 30 oz of milk a day. He should have enough water already. By the way, it may a little bit early to give him congee. My daughter is still have not start the cerel or congee yet. Because my Nanny said that milk is the best food for them. Solid food should be just an introduction only.
