My baby girl who was EBF started daycare at 4 months NOT taking bottles. My silly self gave her a bottle once at 3-4 weeks and she took it no problem. I then thought to myself that she wouldn't have an issue taking them and didn't feed her from bottle again until about 3 months. WELL SHE DIDNT LIKE ANY of them!!!! Daycare had to syringe feed her for about 2 weeks!! I had bought about 5 bottles she did not like ANY and would CRY as soon as it touched her lips. Most of them were a harder material. These ones are nice and soft, more so than what I have tried and she took these ones easily said daycare!!! These were actually suggested by daycare as a last ditch option before just cup feeding her!!!! TRY IT!!!!!!!!!!!!
