Factors to consider when buying Baby Bottle
Most important that the bottles are BPA free.
Second point is they should have some sort of mechsnism to deal with the displacement of the formula with air as the baby drinks because the old solid glass bottles allowed baby to suck in the air and then they would get bad gas pains
Never looked to a celebrity for a bottle because Celebrities don't even have female wives. They're all owned by those manufacturers.
Just Google then read reviews and see which looks best.
