Depends. Part of the reason women and children are first, is because they are considered weaker, needing help by the men to get to a safe place, while the men can in the end help save themselves better than the weaker sex, or dependent children. Also, women are needed to continue the species, and same for children. But, when many many people are going to be able to be saved, I think it becomes more of an every man for himself situation, especially among adults. Young children would likely be protected by their own parents, and some other adults might make an effort to protect and save young children who did not have a parent nearby.
I heard on the recent ship that tipped over a woman handed her baby to a woman who was in a safer place, asking she keep the baby safe. The woman did hold the baby for a while, but then became afraid she would drop the baby and handed it back. Last time I saw her on TV she was asking to know if the baby and parents survived. But that was a baby’s own mother handing over her baby to save its life, asking for help.
