Yesterday we had to make the decision to switch from breast to bottle for our now week old baby daughter. I have some questions about things. 1) I have a tommee Tippee electric steam steriliser and the instruction says they will stay sterile for 24 hours if it is unopened but how long if you open to take a bottle out? There is room for 6 bottles but as you cant make bottled in advance surely they need to stay sterile for a while. 2) how do you keep a bottle sterile while out and about? 3) how do you make fresh feeds when out? 4) what do you do about night feeds as the box of milk says you have to boil the kettle, pour the water and then leave to cool for 30 minutes before adding the powder but surely you don't want to have to wait 30 minutes before feeding a hungry baby. I am sure I had other questions but am exhausted and have forgotten what they were so if you have any tips, hints or things i should know.
