.....and also use the tomee tipee closer to nature bottles, i used the flask for the first time today, and firstly was a bit peeved that the bottle didnt properly fit in the outer flask, but prosume rising steam warmed it, may seem a silly question but do you struggle to get it bak out again, cus their isnt any room around the bottle to grip it, i had to take the lid off and grab teat with a clean tissue,, not ideal as teat was obviously sterile!!
