This Tommee Tippee bottle bag is definitely one of my baby essentials and one that I would really recommend to every parent who is going to use bottles for their baby. I breastfeed my little boy pretty much exclusively for the first six months but now he's got teeth and is not a baby anymore he has bottles. Tommee Tippee bottles are the ones I found that worked best for him but so this bottle bag is definitely perfect for me but I would say that you could fit other makes of small bottles in it too. This bag fits the Tommee Tippee closer to nature bottles. 

The bag is basically just a cylindrical bag which is made of black fabric on the outside and then has the padded silver insulated material in the inside which will obviously keep your bottles either warm or cold, whichever you want.

The bottles fit quite snugly in this bag which I like as it means it keeps them upright well as they don't have room to move around and it means milk doesn't spill out inside as it would if you just carried your bottles in the pocket of a change bag or something like that. I have done that in the past and it's a bit of a pain but with this bag I have no mess. 

The bottle holder has a zip about three quarters of the way around the top so it opens well and allows you to get the bottle in and out easily. There is also a handle At the top which allows you to hook it onto your pushchair or change bag so it's always in a handy available place. 

I find the insulation in the bag works really well. I have put both hot and cold bottles in there and they always keep their temperature well. It's so convenient for me to make up a bottle and put it in here for my little boy for when we are out as then it's ready to go as soon as he needs it and there are no cries until he gets his milk. 

A twin pack of these bottles costs £8 which I think is very good value as these are handy, fairly stylish and clever working bottle bags.
