Baby is still small and her intestine are weak so need to be slow on complementary feeds. Complementary feeding is giving top food which are home made like paste or puree form but most importantly in a step wise manner. From 6 to 9 months, can introduce 5 to 8 items only like curd rice, khichdi, dal rice, meshed potato, fruits, Raab or sheero. But most important is that, it should be introduce in a step wise manner ie one item for a week for a fixed time ie fixed routine. Too many items introduce at same time causes a problem. At this age, 4 times a day is normal. Enterogermina as such no role. Just step down on food items. No bottle feeding too

It's normal phenomenon...no need to worry

U have start solids gradually.....if baby passing urine well,taking feesing well then no need to worry....u can visit pediatrician for physical examination once
