Our little mouse wanted to be always satisfied, but to be more independent, or the daddy sometimes can give the bottle, I wanted a bottle ... After several attempts with different bottles and teats it has in the last Lansinoh folded. The bottle is also very inspired by the chest and the silicone little thicker and softer, I guess, that it's not a blatant change for the babies so. So we were top satisfied. I've got the bottle among friends passed since the little bottle did not take. But with the Lansinoh it worked well with him.
