What are the supererogatory acts of worship and devotions that a pregnant woman can perform to draw closer to God and ask Him for righteous offspring, taking into account the difficulty of prostrating in prayer?

A woman should strive in supplication for the rectification of her offspring, as it is one of the most powerful weapons. She should frequently engage in dhikr (remembrance of Allah), recite the Quran, and perform supererogatory acts of worship (nawafil) as much as she is able. In supererogatory prayers, it is permissible for her to pray sitting and to gesture for prostration if she is in pain. She should also give charity to the poor and needy. The more she strives in worshipping Allah Almighty, the more she will be rewarded, and this is a form of tawassul (seeking nearness to Allah) through righteous deeds.
