Charlie Sheen -- Father of the Year

Charlie Sheen is a fantastic father who dotes over his children and is always there for them ... this according to Denise Richards.

TMZ has obtained a document submitted to the L.A. County Dept. of Children and Family Services, written by Denise Richards. The title is "Visitation Log." Denise outlines Charlie's involvement with Sam and Lola -- the kids they had together, as well as Bob and Max -- the twins he had with Brooke Mueller.

The document -- which Denise was required to keep because she was Charlie's monitor when he visited the twins -- was included in her documents to show DCFS Charlie has been a capable, even excellent parent, whereas Brooke has been a disaster.

Here's the outline of Charlie's involvement:

-- Sept. 22 We all had dinner together. Charlie stayed until bedtime
-- Sept 25 Visit after school till after dinner
-- Sept. 29 We all went to watch our daughters ride, petting zoo, and dinner with friends
-- Oct 2 Boys and their dad and I took the girls to their dance class after school. Bob and Lola put on a dance show for all of us before bed. Their father stayed until bedtime
-- Oct 4 Boys field trip for school. We all went together. Spent the morning until 1:30 PM
-- Oct 6 Charlie was with us for the boys' drum lesson. Watched them play and went to play ball with boys. His friend and sons met us as well
-- Oct 9 I had friends and their children over for a dinner party. Charlie was with us. He left right after bedtime
-- Oct 16 The kids all came to my set at work. Charlie met us there. At my dinner break we all ate together
-- Oct 20 Charlie and his chef came over and she made brunch for us. Sam had a big project for school he spent time working on that. And also did art with boys
-- Oct 23 Dinner/homework with girls. Read stories to the kids
