A HSE panel reviewing child birth complaints in Irish hospitals was set up last year, following revelations of poor care standards at the Midlands Hospital in Portlaoise.
The Sunday Independent reports that the panel examined 80 baby deaths, and decided that 30 of these needed further investigation.
But this figure could increase as more cases are reviewed.
Elsewhere, a review of maternity services at Portiuncula Hospital in Galway announced last week following the deaths of two babies is set to be expanded.
It comes after a further five families came forward to say that their babies died or were left starved of oxygen.
