It is NOT de-worm problem

Oh..well..we came one full circle. Lucas' not so good appetite and loose poo has nothing to do with the de-worm. I went to 2 pharmacies and asked what is the side-effect of de-worm. Both have consistent reply that is nothing. So, I was left wondering what could be wrong. Then it strikes me that I have just switched Lucas' milk to a different brand. The milk he was drinking was getting too expensive and I thought maybe I can save some money if I switched him to a cheaper brand. Lucas sure does not agreed with my idea. Now, he has back to his old brand. I guess I just have to work harder to pay for his milk.
