A question about teats?

So, I have a whole bunch of Nuk #1 dummies (pacifiers) and bottle teats that I put away when Aaron grew out of them.

They have been sealed in a tupperware type container for what must be about 2 years.

My question is: Can I sterilise them and use them for theSQL or should I toss them and buy new ones?

I intend to breastfeed exclusively for the first 6 weeks but then I would like to express and give Paul and Aletta and the grannies etc… a chance to feed her now and then.

I am going to buy new bottles (non branded ones) and use the Nuk teats like I did for Aaron.  Just not sure if I can still use the old teats and dummies?
