The anomaly back then, I switched to GLASS BABY BOTTLES in 2000 with my third child....just an instinct that something was not right with plastic. Anyhow, back then your only option was glass bottles by Gerber (and they were hard to come by). Now, you have the cute option of Wee Go, which has a rubber exterior.
