Apostrophe usage?

I've written:

Special offer: For a limited period (to celebrate the launch of our saunas in Chalet Harriet 1 & 2) we are offering our free children's discounts on both chalets for 15th December and 22nd December.

I particularly want to know if it's "childrens" or "children's" (with or without the apostrophe) and if the brackets above work? Thanks

Solution 1:

It's "children's". "Childrens" is never correct because "children" is already plural. To show something possessed by children, the apostrophe-s is required. IOW, the way you have it in your original text is correct.

For words that are singular but for which you want to show possession by more than one of them, such as fees paid to many lawyers, you would make "lawyer" plural by adding an s, and then make it possessive by adding the apostrophe at the END.

"The settlement money was almost entirely consumed by the lawyers' fees."
