I read this thread with great concern, as I had used polycarbonate bottles and breast pump with my now grown up son, would not have if this knowledge had been available then. However, this is what I have found out from the high street and internet;
Recycling numbers on plastic items (triangle of arrows with a number in it on the bottom of items) indicate what a product is made of . Numbers 1, 2, 4, and 5 are all polyethylene or polyprpylene and are SAFE. Numbers 3 PVC, 6 polystyrene, and 7 polycarbonate and others are NOT SAFE.
Check teething toys are made from safe plastics, and use silicone teats and dummy teats, because latex has a toxin agenda of its own.
Bottles that are safe:
GLASS expressed milk storage - mainly from eco wesites.
MAM ULTIVENT - now available is a compatible manual breast pump,
from Boots and Mothercare World.
MELEDA - bottles and pumps.
MILK STORAGE BAGS.
STERIBOTTLES.
AVENT VIA RECYCLABLE CONTAINERS AND MAGIC CUPS - shame the pump looks like polycarbonate. Smaller magic cups have volume graduations and might be able to replace the spout with a teat for young babies.
CLOSER TO NATURE TOMMEE TIPPEE - breast pump looks as though it's not polycarbonate, but the collection bottle is, if it could be used with a TT EASIFLOW BEAKER it would be BPA free. These beakers have graduation too, but don't know if the spout can be replaced with a teat.
TT also make a TIP IT UP trainer 6m+ and sportster 12m+ beaker with silicone spouts, again don't know if they can be replaced with teats.
BOOTS BOTTLE TO CUP TRAINER same shape as their bottles, but not polycarbonate, may take teats, and has graduations.
MOTHERCARE WIDE NECK BOTTLE TO CUP TRAINER - very similar to the TT closer to nature predecessor, the one with the nubbly teats (nuby) but has handles. A full bottle size with graduations, and a teat.
PLAYTEX PREMIUM NURSER system, with liners, rigid or bag type. These are safe because although the bottle is polycarbonate, the milk never touches it as it is contained in the liner. Used to be available in Toys r us, but didn't see any so may not be popular in U.K. Best bet is online.
Most toddler beakers are safe, but there are a few which look suspect, those which are as transparent as bottles. Basically, if they are cloudy looking, feel slightly flexible or are totally opaque they are O.K.
This was quite a difficult exercise, as not everything is labelled with the material it's made from, or if it is, it's hidden within packaging. I hope that who ever reads this will be able to make an informed choice about baby feeding items.
