My siblings and i All used similac. If i have complications with breastfeeding I'll use it to
Sometimes it does take several to find what works best for your baby.. but the Walmart brand has all the same ingredients as the name brands for much less. I used it in the past and will again this time. My pediatrician said it is just as good.
It all depends on baby. We bought generic similarc bc name brand was so dang expensive. We also had to change to a lactose free with my daughter after realizing the regular made her spit up and she did not like soy. It was a bit of trial and error till we found what worked for her.
ive always used similac.... my girls never liked enfamil....
and well my mom used to send me nan1 but thats from mexico which the doctor told me contains everything similac does
