The new momtold PEOPLE following her son’s birththat Mila and Poppy were “thrilled to have a little brother and already nicknamed his nickname, exclaiming, ‘Welcome to the world, Hal Pal!’”

In fact, their new sibling’s nickname is all his sisters’ doing. “We weren’t exactly sure about the name, but then his big sisters arrived and they called him Hal Pal,” Bush Hager recalledduring a Monday-morning call-into theTodayshow from her maternity leave. “So we thought, ‘This is just perfect!’ ”

Bush Hagertoldher daughters about the pregnancy onEaster Sundaythis year, sharing on theTodayshow that the “Easter bunny brought them an egg with the big reveal.”

“Harold comes from my maternal grandfather, Pa, who I loved dearly and was unable to keep a son long enough to name,” she added.

In the days after his birth, Hal has had visitors from many of Bush Hager’s family members and friends — includinga recent visit fromBush Hager’sTodayco-hostHoda Kotb‘s daughterHaley Joy, and Bush Hager’s twin sister Barbara Pierce Bush Coyne, who brought “donuts and tacos”when she arrived at the hospital.
