my nephews are 18mths and 6yrs old
The 6yr old will put his plate in the sink, clothes in the basket and half tidy up toys but he isnt a natural helper.
The 18mths helps with EVERYTHING. He unpacks the dishwasher (even if they are dirty), folds the washing, puts clothes away (even the ones he is supposed to be putting on after his bath), picks up bits of paper of the floor askes 'bin?' adn then put them in the bed and closes the lid saying 'close lid', picks up the couch cushins and say 'uh-oh' when they fall off couch, attempts to vaccum and sweep, 'helps' wash the dishes and cooking - anything and everything. If we do it he will do it too.
