I used Dr. Browns, which my son loved and adapted well too after i stopped breastfeeding. But I hated them because of all the pieces you had to wash!
I used adri for the best with breastfeeding, but i like the latch n dr browns to
I absolutely loved the Tommee Tippee bottles for my son and I bought more for this baby. They're a really easy shape for tiny hands to grip.
I used nuk and tommee tippee
I used avant for my first when I did bottle feed her or if she was with her dad and my breast wasn't there lol
I used Avent natural and didn't have any trouble with nipple confusion
I used Nuk for my daughter after having breastfed her because the Nuk nipple is the most similar to an actual nipple as far as when it goes into the baby's mouth. She had no problem adjusting to it after a year and half of breastfeeding.
