anyone tried self warming bottle? - Yoomi

Hi, Just came accross this and it sounds like a good idea for night feeds. (if BF doesn't work out for me) Anyone tried it? They're not cheap, but sounds handy. http://heymama.ie/feeding-bottles-acces ... teat-p-155 Anyone recommend/not recommend them? Thanks

Thanks for your reply. You make a lot of sense. Don't think I'll bother with it now.
