I am giving my son who is 2.5 years old Bellamy organic stage 3. He was breastfed until 2 years old. Personally I like the taste of the milk and he accepts it very well, from the transition of breastmilk to formula milk. I choose Bellamy as it is organic and easily available in Singapore. I don't mind to pay a little bit more to let my children to drink organic milk.
LO Bellamy organic step two is very good ... My friend's son is taking it and he loves it. I tried to my son 3yo but he refused it because he is used to his current formula. So, it depends whether your child wanna take it or not.
