Totally confused about sterilising bottles - HELP!

[havingastress]

Ok - so I have checked through back threads, and tbh, that's just confused me further!

Baby is 3 weeks old. Have just stopped bf'ing (upsetting, but just couldn't continue, health issues) so am onto bottles sadly.

We have a tommy tippee steriliser. It says once you open the steriliser the bottles are no longer sterile! Sooo....what are you supposed to do?

This whole boiling the kettle half an hour before the feed is not conduicive to feeding a hungry tiny 3 week old baby.

Can I take ALL of the bottles out of the steriliser, make the bottles up, fill up with cooled boiled water, leave on the side and simply ADD the powder as and when we need them?

OR do we make up all the bottles into milk, leave to cool and then store the bottles in the fridge?

OR do I simply sterilise a bottle at a time and make up just for that feed?

BF'ing was definitely less confusing!!!

HELP PLEASE KNOWLEDGEABLE MUMSNETTERS!!!

rightupmyrue thank you so much for the links. Very clear. Oh I do wish money was no object and I could just buy the ready made stuff!!! Why is it so goddamn expensive?!

However, will be taking ready made out with me with a sterilised bottle for sure! :) Thank you wise mumsnetters!

You're very welcome havingastress.

Hopefully your baby will fall into a feeding pattern pretty quickly so you'll get to know when a fresh feed is likely to be needed so you can get it ready before any major crying has to happen.

You stil can't predict the night feeds though, unless you set your alarm for an hour before you think they might wake. I make my day feeds as needed, but night one have to be made in advance.
