My 姑仔 acts in a similar way too, because she did not have milk to BF her daughter. She always says that formula is the same as ma ma milk because they add a lot of DHA, vitamins etc. and she said that BB is born with 抗體, so ma ma milk is not important!
I know that she knows the advantages of ma ma milk, but she is jealous!
No matter what, I will continue BF (even with very little milk). So everyone should continue & add oil!
Cheers for BF moms!
