Maintaining bone health is important during pregnancy and also requires an adequate intake of vitamin D and calcium. Vitamin K  also helps normal blood clotting. This an important consideration postnatally, so add vitamin K rich foods to your plate in the third trimester. This vitamin is also critical for newborn babies to support normal blood clotting, however babies  naturally have lower levels at birth.
