Hi I'm using Philips avent feeding bottles. Can I still use the old one as I'm using for past 2.5months or go for the new one. Replacing teats every 2-3months but confused with the bottle.

A. You should change the nipple whenever you see a wear or tear or when the nipple changes color or in two months whichever is earlier. I think u r doing this right. Similarly you should change the bottle once in every six months or whenever you notice a discoloration whichever is the earliest.
