Charlie Sheen's Kiddies -- Grandparents to the Rescue!

Charlie Sheen's twins are getting serious back up from the Mueller clan. TMZ has learned Brooke has enlisted her parents to help look after the boys ... and they're flying out to L.A. ... stat.

Sources close to Brooke tell TMZ, Charlie's former mother- and father-in-law are uprooting themselves from Florida to make the trip -- and they're looking for a more permanent place in L.A. at this very moment.

As we previously reported, Charlie and Brooke struck a custody agreement on Thursday -- the terms of which remain confidential ... but it seems Brooke could use some help.

We're also told Brooke is launching a new anti-publicity campaign -- insisting she will make a better effort to shield her kids from the media storm surrounding their father.

So far, no official word from Brooke.
