I had to share my sheer joy and excitement as I know that you ladies may be the only ones who understand. My EBF baby girl refused the bottle since one month old and I returned to work when she was 2 1/2mo. She was going the entire day not eating and then nursing like a monster when I picked her up and through the night. I tried over 9 bottles and cups and researched everything I could to no avail. I ordered the Yoomi bottle and tried it tonight and she took it immediately! I almost cried I was so happy. It has been so stressful getting back into the swing of work and life then to have the worry about my baby not eating was the worst. She refused to suck all the other bottles. So if you are having trouble getting your baby to take the bottle I suggest trying it out. Maybe now I can get a hair cut 😝.
