I had jobs to do around the house (as did my brother and sisters) and we also did this for spending money, the jobs were split between us, washing up, drying, putting away, throwing the hoover round and at weekends sweeping stairs, cleaning bathroom, tidying bedroom etc. Used to get a bonus aswell if we cleaned the car
I "treat" mine when they help me tidy up etc. and thy are only 2
never too young to learn lol
