Is there a concession or solution for parents who face difficulty performing Salah due to their child frequently urinating on their clothes, which leads to them not changing and washing them constantly?

The mother who breastfeeds her child and constantly cares for him, and is afflicted by impurity from him, is excused if she takes precautions and strives to ward off the impurity. It is recommended for her to wash what afflicts her garment if it becomes excessive, or to dedicate a garment for prayer. As for the father, he is not excused for the child's impurity on his garment due to generally not needing to directly handle the child. Both parents must attend to the matter of prayer. The father must perform it in congregation at the mosque with a pure garment, and the mother is excused after taking precautions, and it is preferable for her to dedicate a garment for prayer. They must both repent and make up for missed prayers.
