My DS has never been a fan of TT, but he still gets it every day, although probably not as long or as much as he should. I do do it regularly every morning when I change him. I always moisturize him at this time and he does not seem to mind the TT so much when he is getting a back rub! This way I have been able to extend it longer and longer.
Other things that have worked: placing him on an exercise ball and rolling it gently, putting him on our bed close to the edge with me below and propped on a bf pillow with an activity mat below. When he was a newborn he spent a lot of time lying on my chest (we actually slept that way for over a month) and that seemed to really help develop his neck muscles - he had a strong neck from very early on. We also use a Bumbo. He's not rolling yet (just twisting), but he sat unsupported for the first time today (he's 5 months).
