Should I change the formula?

[Ma.of.Bo]

Hi there,
2 months ago Lo had constipation & boweled every 6-7 days.
I chảnged the formula to Karicare Aptamil Gold, he then poo every 2-3 days w runny green & horrible smell poo for the whole 2 months

I mix feed him. Give him 1 FF a day.
Ive ask GP & she said thats normal for his poo.
But Im thinking thats not.
What do u reckon? Should I change formula again?

Formula can make their poo green and smelly, it's usually the extra iron that does it. Have a look here The scoop on poop!

Does he seem settled on the formula? If it's causing discomfort or wind then it may be worth trying a different one.
