Colorado has become the first U.S. state to offer paid leave specifically for parents with newborns in neonatal intensive care units, implementing a policy in January that provides up to 12 weeks of NICU leave in addition to standard parental leave benefits.

The new law addresses a gap that forces many parents to choose between being present for critically ill newborns and preserving parental leave for when babies come home. Nearly one in 10 babies born in the U.S. are admitted to NICUs, according to the Centers for Disease Control and Prevention. These infants are still learning basic functions like swallowing, breathing independently, and regulating body temperature.

Illinois followed with a more modest approach, enacting legislation that provides 10 to 20 days of unpaid NICU leave starting next month. The Illinois measure received bipartisan support, while Colorado's paid leave passed largely along party lines. Several Republican lawmakers in Illinois became co-sponsors, including those who had personal NICU experiences.

Federal legislation is now being drafted by U.S. Rep. Brittany Pettersen of Colorado, which would add up to 12 weeks of NICU leave to the existing Family and Medical Leave Act. Advocates believe the measure could gain bipartisan support due to the personal nature of NICU experiences across party lines.

Nearly 800 people have applied for Colorado's neonatal care leave since it took effect in January, according to state officials. Medical experts emphasize that parental presence provides significant benefits, with skin-to-skin contact helping slow babies' heart rates, improve breathing, and assist mothers with milk production.

A small number of companies, including Morgan Stanley and Pinterest, have independently adopted dedicated paid NICU leave policies in recent years, but workplace support for NICU families has generally been limited across most employers.
