Children's

Children is the pluralised form. 's show's possesssion so children's is correct.

Childrens is impossible without the apostrophe. It's like saying Mices.

stray apostrophe

's shows possession.

needs to go to bed but can't stop MNing

children's

children is the plural so you add the 's at the end

plurals that already end in s only have the ' at the end otherwise you;d end up with things like "the babies's cots" or something!
