These days every married couple first think about good food, shelter, high wages etc and later on decide to having kids. I don’t know why you think that the only thing that matters in a marriage is having children. Ofcourse, once you are married you should wish to have children but I believe in a succesful marriage all other factors should be considered first.
But pplz r neglecting one important thing that Allah SWT! had taken responsibility for every single living thing on this earth, to feed, raise etc.
Ofcourse Allah alone is the Provider and whatever we get is all from Allah and in His alone’s control, but don’t forget Allah has given us a mind to imagine and plan our lives with good intentions, so we have been given the ability to plan according to what we think may be good for us in the dunya and hereafter and we should work towards it, and then leave what will happen to Allah with firm believe that whatever He does is perfect and the best so whatever will happen will be the best as it is all from Him alone.
let say a married couple planned not to have kid(s) for certain period untill they will achieve a resonable position. Couples completed their studies, Got their own home, good reasonable wages with secure job etc.
Myths 
ask those couples who wasted huge amount like a rain on medicines/medical treatment wishing to get preganent once. Our respected elders have seen more springs season of lifes and whatever they say in this regards is the experience of their life not an air-tales. like some1 said Old is Gold.
Everyone’s case is different. An old one’s experience does not affect someone else’s.
name_105! well i’m not predictive and what i said earlier, that actual happened so thats why i shared otherwise this is not a fun thread/discussion where i came to hav fun, it is serious matter.
We have one more family they belongs from Balochistan. The couples of this family had 13 kidz, two of them died in infant age. Ony 1 bread-winning person raised all 11 kidz. They all completed their studies and some of them working with a reasonable wages. One thing here i would like to share with u which make me laugh. The husband wants to marry another women to have more kidz 
The wife as she told us she had her 1st child when she was 18 yrs old.
I wonder why you keep posting such stuff.
weird advice. So far only few pplz enlighten with valuable commets. 
As per men’s giving advice, i think they loves their wives and don’t wanna se others pplz frustrate their wives by alto falto bukbuk like 'lagta hy larki mein koi kami hay, lagta hay varasti bemari hay, lagta hay ke banj hay etc etc. Pressuring go for second marriage as the first wife can’t get preganent.
Example: couples married since 26 yrs ago.
P.S. Pardon my poor english and no offensive to any1.
