I’m sure they last quite a while, we have some leftover from when our first turned one that keeps til June /July I think. They have best before dates on
I’ve just bought some Kendamil ready to feed bottles for the hospital and I’m 24 weeks too, they don’t expire until October, hope this helps!
as long as the best before dates are far ahead in advance i’m sure you’ll be fine. we used the premade for the first couple of weeks with little one at night time and it was a god send
I really wouldn’t worry until nearer the time with things like this. Maybe when you’re like 34 weeks if you want to get things early. Also the readymade ones have been known to cause constipation so I’d maybe look into this first.
We bought some ready made formula for first few weeks last time but I would highly recommend a tommee tippee perfect prep machine, we picked ours up on facebook marketplace for great price several weeks in. But wish we had just had from start.
Have a look at the best by date next time you're in a supermarket. They aren't refrigerated so I assume they have a fairly long shelf life but it will of course depend on how long they've been on the shelf in a shop as well! X
