Weaning twins from breast to bottle. Which ones?!

[MamaBlue4]

We're weaning our 29 week old twins from breast to bottle. Up until now they've been on nothing but my breasts and fed on demand. I will still feed on demand and tandem feed by breast whenever they're hungry.

It's that time where I need them to start being independent and feeding themselves (I'm weaning on to food as well) and spending time away from me i.e spending a few hours at the DGF's with their siblings or if DH wants to take them out.

We don't use dummies at all only teething rings which they use for comfort instead, so I'm nervous of how they'll take, although I had no problem with other 2 dc going onto bottle.

We use NUK First Choice in Size 2 with medium flow teat for my 2 year old dd's night time routine. And I can't remember what we used for ds1.

I've heard a lot of reviews for MAM nipple teats but I'm not sure which would be best to try.

Are there any MAM bottles that have nipple teats for 0-6 months or 6+, slow flow if possible.

Thanks for any advice, in advance.

I'm also to silk or silicone, not keen on plastic.
