Curious if the allergic tots were born to moms that didn’t much nurse and/or pump. And nursing would be a challenge for a working mom.
The healthiest kids are farm kids. They are exposed to lots of allergens early on. As far as nursing and working, it can be done. I nursed for 15 months and worked. This was before good pumps were available. I had to fill up bottles, the old fashion way(by hand). Even did it at work. It just takes determination. My boy was never sick.
