Parenthood star Erika Christensen is introducing her adorable bundle of joy to the world!

The first-time mom gave birth to a healthy 6 lbs., 3 oz baby girl on June 21, and the actress has taken to Instagram to announce her daughter's name and give fans their first sweet glimpse at the newborn.

"Week one down with the new BFF. Our girl Shane is killing the newborn game," the 33-year-old captioned the shot, which shows the glowing new mom, barefaced and with her hair pulled back into a relaxed topknot, planting a sweet kiss on her daughter's cheek while she supports her head.

Christensen first announced that she was expecting her first child with husband cyclist Cole Maness in March with a teasing tweet before debuting her baby bump for the first time at the premiere ofConfirmation.

"This boy is getting a little sister. A human sister...She'll make her first appearance tomorrow at #Confirmation," the actress captioned the shot, which showed her hugging her dog.

Congratulations to the new parents!
