I don't know if this really counts, but when I went back to school my DH had Tues, Wed, and Thurs off to watch DS. It was really good for them as far as bonding goes. DH has always been a very hands - on Dad, so he pretty much knew what to expect. He took DS to storytime every week. There was only 1 other dad there, so I think he felt kind of weird about that. He makes more comments now about missing DS while he's gone and DS smiles alot more at him. I think it's been a really good experience for them.
