Did my daughter 3, brought to Nicholas the bottle. My daughter is full enthusiastic and has understood the knob immediately. Advantage is that they want to have now filled not always water in the bottle and if you want to feed the water so that it is much easier (bottle can be pressed more easily as the supplied). What I find unfortunate, I had understood that wen the bottle for Baby Born Interactive leads it responds by itself, as in the sleeping bag. Because I gverstandent button to use for the other baby born, so that you then also hear sounds. There is therefore impossible to give the same water and to hear Fütter noise. So it's a bottle not specifically touted as the Baby Born Interactive but for any doll. PITY!
