i still cant believe how informative this thread has become. Thank you soo much everyone for puting your imput in on this topic and a BIG THANKS for a nice friendly debate as some of the other ladies have mentioned already!

( Coming from Germany ) On the back of the box on the formula we use stated in the instructions is never to warm bottles in the microwave because it's a scalding hazard. Also, it says to prepare bottles fresh (never store the milk) and to use cooled down boiled water. It should be cooled down to around 50ºc. It used to be quite a pain waiting for the water to cool down so we got probably the most practical device for formula fed babies out there! It's called the Cool Twister. Takes 80 seconds to cool down boiled water to the ideal temperature. Saves so much time waiting for it to cool on its own or setting it in cold water. Plus, Aurora is much more satisfied since when it comes to her hunger she's not willing to be patient one bit!

so funny because you go to babycenter UK it tell you to sterilize bottles and if you go to babycenter USA tell you just hot soapy water is fine .
i am from france but live in San Francisco for 17 years ( but just move to the UK in December ) anyway in France they sterelize and pretty much follow the same guide line that the UK here ...my mum was horrified to see me just wash the bottles with hot water and use tap water in California ! lol for my first son . We just move here in the UK and castiel was 4 months old and i still do here too .
That people are a little bit paranoiac with the sterelizing and stuff for the first few months i guess its ok ( specially a first time parent ! ) but when they start to put everything in there mouth and play with anything their little fingers can grasp not much you can do about controlling the bacteria around anyway ! adding a older sibling that comes and go from outside and then come and play with his baby brother to the mix = battle lost anyway lol .
Did anyone watch the movie" Babies " ? A look at one year in the life of four babies from around the world, from Mongolia to Namibia to San Francisco to Tokyo.
Very interesting to watch !
