You may find it amusing that your husband can have an exaggerated sense of celebration of small things he does.
For 10 to 15 minutes, he could work in the kitchen or sit with the children to help them with their home work... and then act as if he did all the dishes, made breakfast and in fact lifted the mountain on his shoulders.
It's a harmless act, in fact quite amusing if you looked at it without being affected.
Don't be surprised if he asks you for a cup of coffee after that miscellaneous work he did without breaking a sweat.
It's just that nature has made him think that his work is outside the home. True to an extent though when he went to hunt hundreds of years ago.
Don't be upset, he can be trained to do better that this.
Appreciate him for what he does and see his interest grow in household chores.
