hi

i am 29 weeks pregnant

will be just bottle feeding this one
just getting orgnaized
with dd made them all up in the fridge night before heard there is new guidlines about doindthis and that u should only make up as you go along
was thinking especially with night feeds if you make up as you go along wont it be too hot how do you cool down?

thermometre not working properly

the only prob ive found is that some vitamins could be reduced but im gonna have a look at what and how much i have a 13yr old and a 10yr old and now a 5mth old and have always made bottles at the time there needed but have also pre made a bottle when going out incase its been needed on occasions it has and have never had a prob with the kids
