Don't echidnas and platypuses also lay eggs and feed their young milk?

Yes, but all mammals by definition produce milk

Thing is this isn't even the second time mothers secreting food for babies has evolved - some birds do it as well as mammals (birds are basically just mammals 2.0 really, warm blooded, big brains, produce milk, highly active)

What birds give milk to their kids?

[–] [email protected] 4 points 8 months ago* (last edited 8 months ago)

Pigeons/doves, flamingos, penguins

Birds have big brains?

[–] [email protected] 4 points 8 months ago

They don’t, but their neuron density is similar to some primates.

How else do you think they remember the directions to their summer home every year?

[–] [email protected] 6 points 8 months ago* (last edited 8 months ago)

Yes, and?

Edit: before this we knew of two groups of alive things that produce milk: mammals and monotremes (egg laying mammals). Finding an amphibian that also does it is very interesting.
