Busy Phillips is having a pretty full week; just two days before Independence Day, she gave birth to her second child, a baby girl who weighed 8.5 pounds.

Phillips, who is already mom to 5-year old Birdie with husband Marc Silverstein, tweeted the good news on Wednesday, along with a photo of herself and her sweet girl.

Phillips spoke about her second pregnancy in April to Us Magazine, saying it was a totally different experience from her first.

“I thought this pregnancy would be like the first one and be easy, but it’s been completely different. I’m even losing my voice because I have acid reflux!” she said. “It’s so gross. Your body is just highjacked. It’s gross.”

The actress also talked about how her daughter felt about being a big sister and said she was excited.

“She’s actually incredibly helpful and … she’s really understanding things, when I say like, ‘Mom can’t carry you right now because the baby in her tummy is pressing down on her bladder!’ She understands what that means and she’s cool with it.”

The baby’s name hasn’t been released yet, but Phillips’ rep says that both are healthy and are doing well.
