The site is being weird today... keeps on giving me errors too!
wooohooo Champers! Sounds like you are going to have an awesome weekend.. and its your birthday!
Silicone or latex... i have no idea.
Be careful of the "starter sets" rather spend that money and buy only big bottles ( i think they are 240ml) . If you are going to breast feed for a while you wont really use the small bottles for very long... i remember with Mikayla that i thought it was a waste...
Thermometer - yes you will definitely need one! a standard one that you can stick under baby's arm will do the trick. I have used it 100's of times with Mikayla. Definitely worth the money but you really dont need an expensive one.
Bottle warmer - not necessary in my opinion. I use to warm mik's bottle's with warm water in a jug. That is how i defrosted the breast milk as well. I understood that that is the safest way to defrost / warm the breast milk without destroying all the good stuff.
We are pretty close... its very excited! I keep on thinking 24 weeks and baby is viable...
