Solids why the rush?

I feel like a lot of you guys are rushing to give your babys solids. Why is that? Is there a benefit to giving them solids so soon? What is your reasoning? Do you know the recommendations and just choose not to follow? Or do you not know what the recommendations are?? NO BASHING OK?! I’m a ftm and i genuinely want to see what everyone else is thinking so i can try my best to make a decision. All the research i read says 6 months to give them a chance to have their stomachs develop better to digest food the best way but a lot of moms here are starting at 3-4 months. My hubby suffers from ibs and was given solids early as a baby, seeing him suffer breaks my heart!!! 😥😥😥 i wouldn’t want to feed my baby too soon and have that happen to him as well!! Please and thank you!! Again, no bashing!!!! 😌
