My 3yo ds (4 in April) is expected to, brush his teeth then I will take over from it, he toilets himself has a go at wiping then I will wipe as well, put his shoes away (when reminded) have a go at dressing himself still has trouble with shirts, feeds himself then take his own dishes to the sink, put any of his own rubbish to the bin. Pack away his toys with help.
He also occasionally sets the table for dinner and helps with preparations for dinner but likes doing this.
I grew up the baby of the family were everything was done for me, it made me lazy in a way and looking back wish I was given chores to do as it was such a shock when I grew up and had to do it myself.
