Girls, we're on IV. What mixture helps with constipation. Our pediatrician advised us Semilak comfort but every time she got nauseous. Then after two weeks until today, she started giving Nutrilon premium and everything was good, and the weight gained, and gas seemed like not much, but now for five days she can't poop by herself. Before that, she would poop once or twice a day.
