Are bottles harmful to babies?

Parents have been feeding their babies with plastic bottle for years, but new evidence is emerging that clear plastic bottles may be harmful to a baby's health. It all comes down to a checmical known as bisphenol A, which The National Toxicology Program Center for the Evaluation of Risks to Human Reproduction is concerned can cause problems to fetuses in utero, including birth defects. The full report won't be available until later this year but they've provided a brief summary.

Meanwhile, bottle manufacturers have been quick to point out that the findings so far don't mention many major risk, so they're telling us to keep using plastic bottles. Do you think it's a good idea, or should we switch to something else in the interest of safety?
