I was planning on trying to breastfeed when my twins were born but after a hard delivery it took my body a while to recover resulting in babies being cup fed as well as my attempts at feeding. This led to them both learning to lap like little kittens and would no longer breastfeed or take a normal shaped teat. A midwife suggested bottle feeding with NUK teats to teach them how to feed again as the shape allows them to suck in the same way, it worked like a dream and from a few days old they could feed from me and take their formula top ups from a NUK teat.

The bottle
-Material
The bottles are made of polypropylene plastic which is BPA free.
-Neck shape
NUK bottles come in a both First Choice wide neck or standard neck. The bottles we bought were the wide neck ones that our local Boots sold. The wide neck is easier to poor boiling water into and add the scoops of powder, when you've hardly slept for what feels like forever anything that makes it easier is good!
-Size
The bottles also come in a choice of 3 sizes 150ml/5oz, 240ml/8oz or 300ml/10oz. We started out with the 150ml size and as we were only using them to top up babies feeds they were plenty big enough. When I stopped breast feeding at 9 months I looked into buying a larger bottles. The most they were having at one feed was 210ml so the 240ml was what I wanted, unfortunately I could only find this size available for sale in glass. As bottles were frequently being knocked over I decided that this wouldn't be suitable for us, so instead I purchased a pack of 3 x 300ml bottles from the NUK website.
-Markings
The bottles are clear apart from a ring of coloured pattern round the bottom, NUK written at the top and the markings from 30ml/1oz up to the maximum fill for that bottle size. None of these markings have faded and we have used the original bottles everyday for the last 10 months. With all the washing and sterilising they've been through I'm really pleased with the durability of them.
-Shape
The bottles are slightly curved and comfortable to hold even when feeding 2 babies at once. My 2 can now easily hold the bottles themselves and have been able to since about a year.

The Teat
-Material
Again NUK offer a choice, either latex or silicone teats. The twins had been used to the latex teat in hospital and luckily this is what the bottles we bought came with. The 300ml bottles we bought came with 0-6 month silicone teats so we had to also buy the latex teats as there was no option to buy with these. It is recommended that the teats are replaced every 1-2 months but I did find with our low usage that it was longer than that before the latex started to deteriorate, becoming slightly sticky.
-Size
The teats come in 2 sizes 0-6 months (size 1) and 6-18 months (size 2) We found 6 months was about the right age for making a change in size. We've used the teats for expressed milk, first milk and cows milk without any problems.
-Shape
They have an unusual shape compared to other bottle types which allows baby to suck in the same way that they would when breast feeding. I like the fact that the teats are approved by the British Dental Health Foundation. The teat is shaped so that it has to be held in the correct position for baby to feed. You can tell which way is up by the anti-colic valve, a hole at the edge of the teat. Both babies had colic but I wasn't using the bottles enough at that stage to say if it made any difference.

Sealing discs
The bottles come with a disc that sits in the top of the bottle so you can transport it without leakage. I always kept bottles upright to be on the safe side. When I bought the large bottles they also came with flat caps you could screw on instead of the teat which made storage of the bottle easier.

Cleaning
We've always used washing up liquid and a bottle brush to wash the bottles up with. When we needed to sterilise them they fitted into the steriliser we had already bought which was for wide necked bottles. The teat is easily removed from it's coloured holder for cleaning.

Colours
The bottles come in different colours, we had half red and half blue so we knew which belonged to which baby.

Price
The NUK website regularly has the bottles on offer and the 300ml ones are currently £12.25. Boots often have the teats on a 3 for 2 offer so I try and buy them then.

I've been really pleased with these bottles and would recommend them to anyone looking to combine breast and bottle feeding.
