I started with 1 tin of S26 right after baby came back from hospital. Then switched to Enfamil 0-6months. Then NAN 6-12months. Around 11 months I tried Nature One and Dulac as well. She seems to be taking Dulac better. Then I had free samples of Dumex Mamil Gold. Right from there she’s been drinking Mamil Gold. She’s 14 months now. That’s 6 different tries of formula milk. Lol.
