They don't recommend keeping feeds in the fridge anymore lucusmum. Stupid as when I had Zack we were told to make up feeds in advance and keep them in the fridge and Zack never died. Crazy how much things change. I used to make up like 6 feeds at a time with him and whack them in the fridge for the day. Just heat them up then when he was hungry.
Oh wow I didn't know that so the perfect prep only takes moments to make a bottle? I'm not sure I'd function well enough during the night to make a bottle up
