These include but are not limited to pregnancy in the very young, pregnancy in older women, births that are spaced very close together, and high parity births (births that occur in a woman who has already given birth many times).
In developing countries, children born two years or earlier after an older sibling were at a 60% increased risk of death in infancy, while those born between two and three years had a 10% increase, compared with those born after intervals of four to five years.
