AKIPRESS.COM - Illinois Senator Tammy Duckworth brought her baby to the floor of the US Congress' upper chamber on April 20.

Wearing a pink bonnet, Maile was allowed into the chamber after rules were changed the day before.

The US Senate has agreed new rules that allow members to bring infants into the chamber when they vote, BBC reported.

The move comes a week after Tammy Duckworth became the first sitting US senator to give birth while in office.

She had expressed concern about how she would be able to care for her newborn daughter while carrying out her constitutional duties.

Senators said it was important that they led by example by introducing family-friendly policies.

The change was approved unanimously.
