Hi Mo I use Pigeon bottles that come with a Peristaltic nipple/teat. Supoosedly the teat is softer therefore flexible and as your baby sucks it stretches like your own nipple would do in their mouth. I did have the Avent bottle range (teats, dummies etc) but Maddison's mouth is too small and she would gag cos it didn't fit and she couldn't latch on. The pigeon bottle also come in a wide neck range with the peristaltic nipple. I have 4 x 150ml and 3 x 250ml bottles plus a 330 ml avent bottle. I use the avent bottle and large bottles tp pre-make the formula and then pour out what is required into the smaller bottles. I use the avent electric steam sterlizer and wash and steam the bottles in the morning and then at night. Maddison has six 100-130ml feeds a day. I hope you don't end up in hospital, just think you did a great to BF for as long as you did....
