My child wouldn’t take ANY bottles. He acted like he didn’t know how to suck (but he breastfed just fine). This is the ONLY bottle I’ve had success with. I just wanted the option to have someone else feed him in the event I wanted to be out during a feed and it did the trick. Will definitely recommend to my NICU community too, I think it will be beneficial for the moms that aren’t producing enough milk (had that issue with my first).
