Err, 7 kali sehari tu agak banyak jugak for a 6-month-old, normally at this age diorang yang makan solids should be around 1-2 kali sehari, especially kalau texture nya normal mcm you describe (bukan cirit-birit). A few of my mum friends pernah kena situation camni, and turns out either dia adjust to new food, or ada slight issue with digestion. Best la you check with your pediatrician to rule out anything, sebab changes in poop frequency macam ni kena investigate slightly, even if the consistency looks okay to you.
