S.H.
1 year olds, do not sit still.
Their attention spans are not even fully developed.
Not even 6 year olds sit still.
Kids, need activity... that is physical activity. This helps them develop and it also get out their pent up energy... and they can nap... better.
Just hop around, put on music and "dance" to the beat, kids this age can learn "rhythm" for example. Play follow the leader. Roll a ball back and forth. Put pillows on the floor and let her hop on it in a path. Make pretend houses using sheets and blankets and big boxes.
The best time for energetic play is in the morning. Then have a mid-morning snack. Then an early lunch by 11:00am. Then... nap time. Then the afternoon can be quiet time or just independent play.
Kids ALSO need to have, their own play too. Meaning, letting THEM... just explore and do things without it being all done for them. This is all a part of them developing skills.
