I would without a second thought.

I'm quite lax about those kind of things in general though so interested to see what others say.

Share them! No issues. I did have white bottle tops for DD and black for DS but would happily give some of one bottle to the other in the circumstance you’ve mentioned.

What I wouldn’t do is share all bottles as then you wouldn’t really know how much each baby was taking unless you made a mental note in your head (and I’d defo forget that)!

I used to do this all the time, I used to feed them at the same time. They're almost two now and share each other's drinking cups, the just pick up whichever they come to first.
