hi J.,
well i too have an active 2 year old (he is now 2, 9months - a few months ago i started laying out his clothes the night before so that right after he wakes up (which is 99% of the time happy) we would get dressed BEFORE coming downstairs - it has worked like a charm - he may say no, but there is no major protest as there was before when we would be downstairs in PJ's after breakfast and playing.
as far as other dressing sessions & diapers - i just tell him we cannot play until it is done so....hope it helps a bit!
