Overnight trip - bottle advice?

[Anonymouslyconercned]

Hi ladies
I’m staying overnight for a wedding in a couple of weeks. Baby is nearly 4 months.
What am I meant to do about bottles, as in how am I meant to wash and sterilise during an event like a wedding.
im only staying in a normal premier inn hotel so won’t have access to a sink lol to wash up the bottles even if I did want to use the cold water sterilisation I still won’t be able to clean the bottles first.
I looked at the ready liquid formulas but they’re only 70ml and she’s on 150ml at the min and could be on more by the time the wedding is here so that means like 3 bottles in one go …
if you can’t tell I am a FTM, but genuinely so confused about what I’m meant to do here lol …

Why can’t you use the sink in the bathroom to was them?

you used to be able to get sterilising bags but I’m going back 10 years so don’t know what is available now

Wash in the bathroom sink and get the Milton single steriliser

Of course the room has a sink - in the bathroom! You can bring a bottle brush, washing up liquid and tea towel from home and then either cold water or plug in electric steriliser from home.

If it’s just one night though then sterilise enough bottles before you go and take them empty in your bag and pour out the ready made formula when baby needs a feed. Wash them up when you get home and avoid the faff. You can store an open container of ready made formula in a fridge for 24 hours but I don’t know if you’ll have access to
a fridge, and then you’d probably need to warm the bottle... A wedding is enough of a one off though, so I’d treat it like a long flight and just be prepared to chuck the leftovers for ease. At 4MO my babies were having 5-6oz per feed and the bottles are 7 so there wasn’t there really wasn’t that much wasted.

Most brands make ready made bottles in 200ml size too.

I have the Milton cold water sterilising tub thing but anything that holds 5l of water will work with Milton cold water tablets. I use it as a washing up bowl too, rather than a hotel sink. Take some fairy liquid and a tea towel or two.
Easy!

Cold water sterilise using bathroom sink water. There's usually a kettle so you can boil water if you take powder. Or take lots of cartons and just take sterilised bottles with you

We did cold water sterilisation in the bathroom sink too. Took a bottle brush and a small bottle of detergent or milk buster spray. I preferred the 200 ml readymade cartons while travelling, especially at night and out and about rather than faffing around with the kettle (used perfect prep at home).
