Ur answer lacks hikma.I say give birth as soon as possible when you are physically capable of having children without harm, and have as many children as you possibly can. The more Muslims have children, the better it is since you are growing this Ummah and we need to increase our birth rates to have a powerful influence in any land Muslims reside in. So if you are able to give birth to 14 children then give birth to 14 children. If your body is strong enough to give birth to more children then I would recommend doing that as well.
Abu Dawood (2050) narrated that Ma’qil ibn Yasaar said: A man came to the Prophet and said, “I have found a woman who is of good lineage and is beautiful, but she does not bear children. Should I marry her?” He said, “No.” Then he came again with the same question and he told him not to marry her. Then he came a third time with the same question and he said: “Marry those who are loving and fertile, for I will be proud of your great numbers before the other nations.” Classed as saheeh by al-Albaani in Irwa’ al-Ghaleel, 1784.
This Hadith indicates that it is encouraged to marry women who are fertile, so that the numbers of the ummah will increase, and so the Prophet ﷺ will feel proud of his ummah before all other nations. This shows that it is encouraged to have a lot of children.
When u have a religious ruling you need to be apply it in different circumstances and situations and understand the different rulings that come about because of that. Although the principle you stated is correct the application is completely wrong, with all due respect leave these questions for people of knowledge to answer as they will have a comprehensive knowledge of the entire religion and state of affairs for our ummah now to apply them properly. Some problems with your reply.
1.Having as many children as possible will hinder other things in your life, like your health, like prioritising time to specific children and raising them properly, and taking care of them.
2.Having alot of children especially in the west makes it more difficult to raise properly,most will be sent to schools to be educated on nonsense and learn manners from non-muslims for a good 20 years of their life, having more children makes it harder to de-brainwash them
3.Not all women have the patience for having that many children nor does the people around them, it may not be feasible to support all their children
4.Woman should try have as many children as they can as long as they can raise them properly, I think it depends on time and place, its specific to each woman, there is an obvious trend of Muslims in west having less and less children which i am completely against, but you still have to understand everyone is different. The ideal birthrate for Muslims should be around 5-6, and there should be proper support for mothers by their family and wider society which right now there is not.
