Girls, please recommend a good pediatrician and neurologist, I beg you ? Today we were at the Scientific Center of Pediatrics paid for everything but honestly I regret that I wasted money ? The pediatrician said that I should follow a diet, that breast milk can't be given to the child especially from jars, although I have been giving it for a month and there has been no allergies. I also talked about many other things, I am just shocked, to be honest.
