Ready made formula aptamil - how to store?

[Elleare]

Hi,

I am planning on bottle feeding and I am going to take the ready made bottles of formula into the hospital with me.
This might be a silly question but do I need to store these in the fridge if they have been up opened? or can I leave them in my hospital bag until ready to feed?

Thanks.

Sorry that was meant to say. *un-opened?

No, they only require fridge if you open them and don’t use all the feed. I’m a paeds nurse and they are stored in a cabinet at work. We chuck anything not used - they are only 90ml (3oz) or so so most babies dependant on age) use one or 2 so you shouldn’t need to store excess just use a new bottle.
