The best advice I was given when my daughter was born was to not only put away hobbies, but to remove them from view. Suggestions I was given where things like: packing up the game console and games and put them in the closet, donated the pile of books that I was never going to read, and clear desks/shelves, etc that contained unfinished projects. The first few months there wasn't time for any of that anyway and then as I began to have time I took out the few items that I really wanted to use, but all the while I didn't have a constant pile of fun things around the house making me feel bad because I didn't have time to play with them. Depending on the circumstances you will have different amounts of time, but most importantly is realizing that you will have less time and taking steps to adjust to your new role.
