It is reflected in the 1925 Southern Baptist Faith and Message. So it seems to be present in all the major Christian traditions. Nevertheless there are certainly people who object to it. I think the issue that is most controversial is the fate of children who die in infancy. Catholic theology has held that baptism is necessary for salvation.
Catholic tradition says that unbaptized infants go to limbo.
This is in theory a part of hell. But it does not contain any actual suffering. The idea is that unbaptized infants have not committed any actual sins yet, so there is nothing to be punished for. But because they are not baptized, they are incapable of the supernatural virtues which come only from God's grace. Note that limbo is officially considered speculative.
