With dc 1 and 2 I would get ready made formula and it was in little cartons which I could rinse and put in the recycling.
With dc3 I’ve noticed it is now all plastic bottles - which yes I can still rinse and recycle but isn’t plastic worse? Or is it more recyclable than the old style cartons (I assume they were paper lined with something ?) . I wish we could use powder but it doesn’t agree with them and I’m just worrying now about how much plastic is going in my recycling !!
