Im a Stress-Head & Have Recently Been Panicking Over How To Bottle Feed. Iv Been Asking In "Ask a Mum" About The Best Way To Warm & Prepare Bottles etc But Theres So Much More To It & I Would Really Appreciate Knowing Everything Like.. Night Feeds - Am I Supposed To Get Up & Prepare The Bottle From Scratch Just Like I Will Be In The Day? Or Is There Another Way? Everything I Need To Make Feeds Will Be Downstairs & You've Got To Be So Careful With All This Sterilising etc So Im Guessing I Cant Keep Anything Upstairs Ready? For Example - If I Kept 2 Bottles Of Warm Water In My Thermo Bag & Then Just Add Formula When She Wakes? But Thern There's The Issue Of It Not Being Sterilised Anymore I Suppose So I Guess Thats a No. Going Out - Iv Got An Avent Thermo Bag Thingy That Can Hold 2 Bottles So Would I Put Warm Water In Them and Add Formula When I Need It? The Only Thing About This Is That Once You've Sterilised a Bottle Ready To Go Out.. How Does That Work Because They Only Stay Sterile For a Few Hours and You Cant Sterilise Them If Your Out And About What Do You Do?
