K.R.
she seems eager so go with it!! At least to start learning the basics, introducing the chair could be a fun idea for her, This could work out really well!!! Wearing pants like you said in the meantime could help with keeping the diaper on until you start really getting into the training (once she is a stronger walker)... But she is probably ready to start trying and learning some of it :) Best of luck! I LOVE the duct tape thought!
