Warm milk and sippy cups?

[Olive]

i was meaning the fact that some plastic isnt ment to be heated up, mainly the cheaper plastics, the tupperwear ones would be fine!!

Thanks, that's my main concern too with the plastic not meant to be heated up due to cancer risks etc etc. What are the tupperware ones like? I'm not heating it up alot, just warmish so that it is nicer to drink.

I just bought a magmag bottle that has interchanging lids to a sippy cup then a straw. It is a #5 plastic bottle (a 'good' plastic if you are worried about BPA) and it suitable for warm liquids.

Sweetpea, just make sure you stay away from any cups that are made from "numbers" 3,6, and 7. These so far are considered to be "unsafe".

Unfortunately tupperware will not disclose to you as to which numbers they make their products from, so personally i would stay away.

from thegreenguide.com:

Plastics to Avoid
#3 PVC
#3 polyvinyl chloride (PVC) is often used frequently in cling wraps for meat. However, PVC contains softeners called phthalates that interfere with hormonal development, and its manufacture and incineration release dioxin, a potent carcinogen and hormone disruptor. Vinyl chloride, the primary building block of PVC, is a known human carcinogen that also poses a threat to workers during manufacture.
#6 PS
Extruded polystyrene (#6 PS; commonly known as Styrofoam) is used in take-out containers and cups, and non-extruded PS is used in clear disposable takeout containers, disposable plastic cutlery and cups. Both forms of PS can leach styrene into food; styrene is considered a possible human carcinogen by the International Agency for Research on Cancer. It may also disrupt hormones or affect reproduction.
#7 PC
#7 Polycarbonate (PC) is found in baby bottles, 5-gallon water bottles, water-cooler bottles and the epoxy linings of tin food cans. PC is composed of a hormone-disrupting chemical called bisphenol A, which has been linked to a wide variety of problems such as cancer and obesity.

I heat Harrison's milk up on the stove and then put it into his sippy cup. He only has it warm enough to take the chill off it, especially on cold days where the last thing I want is a cold drink.

Hi there!

Tupperware demonstrator here and I dont have the answer for you now but i will do my best to find out for you the 'number' of the plastics used in tupperware.
I have asked many questions about the plastic for my own sake and I do know that all tupperware is made from Water based plastics and water based silicon and all of the colouring is food dye!

I will put my feelers out and see what else i can find out for you!
