You could also consider the Tommee Tippee travel flask. I got mine for £7 from Amazon. The advantages of this would be:-
- You will probably want a travel warmer anyway, for when you get out and about. I found it really frustrating that 'health and safety' dictated that I was not allowed to be given a jug of hot water myself. So the staff would warm my bottle for me. This would result in the bottle being still cold, or boiling hot cos they had forgotten about it. Much easier to just have your own arrangements stashed in the changing bag.
- Prepare the flask at night and you can use it to heat the bottle in whatever room you are feeding in.
So, it kind of kills two birds with one stone.
If you also had a coolbox you could store the night feed(s) in the coolbox in the bedroom, and then you wouldnt even have to go downstairs in the night at all!
