When to apply Nationality for Kids

[iworker]

Asking for a friend.
Main applicant granted ILR Sept 2015.
Wife and 2 daughters (born outside UK) granted ilr Feb 2016.
Father granted nationality Dec 2016.

Now i understand that since father has the British nationality, the wife can apply for nationality now and doesnt have to wait to complete her 1 year on ilr. Is this correct?
Also do the kids have to wait for 1 year on ilr or they can apply for nationality too? one kid is over 17 but less than 18. The other kid is 14.
Also please advise which form to use for kids.

Thanks.

Also do the kids have to wait for 1 year on ilr or they can apply for nationality too? one kid is over 17 but less than 18. The other kid is 14.
Also please advise which form to use for kids. Form MN1 for kids and no, they don't have to wait, they can apply with mother.

Thanks.
