We have now so many specialists associated with pregnancy, childbirth, lactating, parenting and so on.
As if these are diseases. These are normal biological stages of life. All organisms have been undergoing these life stages since millions of years. Otherwise I and you would not have been here!
So, there is no doubt at all on whether our body can handle these life stages.
But, by ignoring the body for many years, humans are becoming incapable in these activities. And this little weakness is exploited by the so called experts to run their businesses. This is the reason for so many c section births, ICU care of children and so on.
But none of this is needed.
Want evidence, look at millions of years of history of reproduction in all animals without any assistance.
Reproduction is no more difficult than breathing. If it looks like, you have made it to be mostly. The only thing we have is our body, the more we give it to specialists, the more it will be deteriorated.
Take care of the body and all these life stages will be as easy breathing. One of my patient who was following my diet and lifestyle improvements suggestions had absolutely easy second pregnancy, normal childbirth and enjoying lactation now. She told me all this is due to diet and lifestyle improvements. She had difficult first pregnancy which she attributed to listening to experts and seniors at home.
Look at all the animals around who breeze through pregnancy, whelping and lactating. No need of assistance at all. These follow diet and lifestyle their body has evolved to function optimally with. If these animals can reproduce so easily, humans too can.
Start working on your needs, pregnancy will just happen.
