The 11-week-old daughter of Zac Hanson and his wife Kate arrived just before Christmas, and her proud parents say it’s been a smooth, happy ride ever since.

“Junia is such a sweet gift,” says the Hanson drummer, 25, who also has a son Shepherd, who turns 3 in May. “It has been so much fun to get to know her and to watch her along with her big brother grow and change so quickly.”

These days, Zac is likely tops on his 5½-year-old niece Penelope‘s list — until now, Taylor Hanson‘s daughter, been holding her own as the lone lady among six little boys in the family (her three brothers and as many boy cousins).
