@Sina no mother would, and under normal circumstances neither would medical staff. As the article states, staff were pleading for help.

These babies were in an Intensive Care unit. Most were premature babies who were supposed to be in incubators. They are vulnerable and need to be kept warm, may be tube fed or require oxygen. It’s difficult for parents, who usually cannot be there all the time.

It is more likely that the mothers were unable to get to the ICU. We do not yet know how many died trying.
