As a landlord, I always appreciate the tenants who can give me suggested times for showings. I understand that life/kids/etc gets in the way of having the house ready at the drop of a hat. As long as you're not overly stingy with the times you're available to show it, then it should be fine. If you can commit to a certain time frame for certain days, IME, that helps - say, MWF between 3&5 or something, with more flexibility on the weekends and willingness to work with them if they have someone who cannot view the place at your listed times.
Also, make sure you talk to them and see what their understanding is of the notice issue. If you're all on the same page, if makes it much easier. My last tenants to move out made it clear that they were fine with me calling when I had someone interested, and asking if it was an okay time to come over (they didn't have kids). Other tenants have requested that I only show in the evenings and weekends.
Good luck!
