I have two sons and my wife is the major care taker of them. I always plan to give rest to her by taking care of all our house hold activities and child care, but it is merely impossible, because she is having experience in it. Also the kids have more attachment with mother than father. Little kids always need mother's hug, care and affection a lot. It is impossible to live them far away from the mother. So it is very hard to give rest to such kind of home makers.
If we want to help our wife we may share their work, by doing little helps in their kitchen work and child caring, by dressing the kid, chopping the vegetables, serving the food, helping in cooking and some other little works like this. It will give some relaxation as well as pleasure to them. In this way we will give them a little break from their huge work
