Is it normal not to have a bowel movement for seven days? My daughter was born six months and two days ago, and I felt that my body did not produce much breast milk, and there was not enough for her to eat every day. She didn't have teeth yet, and I was going to feed her some porridge, not knowing whether such a small baby eating porridge would cause constipation. Anyway, she has not been for a week, so worried, is it a problem of improper feeding? What should a six-month-old baby eat, is it high-speed rail rice flour or milk goat milk? Brothers and sisters passing by give some advice.
