Havent started Eithan TT yet, but when we TT Bella, once she was day trained, we had her in undies, which she hated. We only used the pull-ups for night time, as I didnt want to continually change the bed, eventually we put her in undies for bed and despite a few accidents she was fine. I must say though she was very embarrasssing in her undies when we took her out, she used to ALWAYS complain about having a wedgie and once she proceded to take everything off in the supermarket, when I had my hands full.LOL
