I'm supplementing my 6 month old with Enfapro A+. Yung Nestogen, you can give it a try sis baka maging ok naman baby mo. Sometimes expensive milk dont guarantee that your baby will be healthier. I understand your dilemma sis, formulas are really very expensive kaya I exclusively breastfed my daughter from when she was born. Now, she's still breastfed, supplemented lang by formula kaya once a day lang sya nagdi-drink non.
Explore other options sis like if you have med rep friends, they can sell formulas at a cheaper price.
