Hi Dawn - sorry to hear they weren't keeping in mind future things with your prescriptions.
We like the Avent range in this house and everything is interchangeable - ie you can add handles and sippy spouts to the bottles later on.
We have gotten by on three small bottles (150ml) and two large ones (260ml). Once baby gets older though you will find you need more of the big bottles. You will need about four No 1 teats. Bottle sealing caps are also a good idea, as is a good bottle brush (esp for baby bottles). Oh and sterilisters as mentioned previously.
We use the Heinz Nuture formula. It's on special regularly at Pak n Save. We haven't had any problems with any formulas.
Hoping all goes well for you and the birth of your lovely bubby!
