1 & 2 can be done in a loving caring way or in a dictatorial way.
3 - that $ucks. maybe buy him a recipe book or sign him up for a free cooking class
4 - that is a reasonable complaint. No one needs to be yelled at or made feel stupid and insignificant. If your daughter has dyslexia she already has a heightened sense of people thinking she's stupid. There is a productive caring way to approach it rather than saying she should know that.
