She’s been busy caring for her first child, a baby girl.

And Scarlett Johansson put comfort first as she stepped out to run errands in Los Angeles on Saturday.

The 30-year-old actress swathed her fantastic post-baby figure in a baggy sleeveless top and sweatpants as she shuffled out of the bank in very casual black sandals.

The Captain America star also sported rather dishevelled and frizzy hair, while concealing her eyes behind round black sunglasses.

She clutched a thick gold wallet while heading back to her vehicle during the solo jaunt.

It’s no wonder Scarlett was keeping it casual, as she has described motherhood as ‘exhausting,’ albeit ‘very, very magical’ when speaking with Barbara Walters in December.

 

At another point in the day, the blonde beauty was accompanied by her husband, Romain Dauriac, and their five-month-old baby girl Rose Dorothy as they headed to a Mexican restaurant in LA.

And while a show of Valentine’s love hadn’t been reserved for just her this year, Scarlett looked beyond content as the trip stepped out for a sunsoaked family date.

Romain, dressed ever-so coolly in a white V-neck T-shirt and black wayfarers, swung his adorable tot up in the air to give her a kiss.

Equally carefree, he went without socks in a pair of penny loafers, matching his wife’s stylish flair.

Doting parents: Scarlett smiled as Romain gave their daughter a sweet kiss while lifting her into the air

Rose was brighter than her achingly cool parents and was dressed in neon trainers and bright pink trousers.

Meanwhile, Scarlett was initially surprised by her newborn daughter’s appearance.

‘When she came out of me I was so surprised,’ the mother-of-one recently told W Magazine.

‘I had a very strong picture in my mind of what my baby would look like, and, of course, she is completely different. Perfect, but not what I’d imagined.’

Looking trim: The actress showed off her slim legs in a pair of jeans and a casual black T-shirt

Driver’s seat: Scarlett left the daddy duties to Romain and took the driver’s seat on the ride instead

Taking the driver’s seat on Saturday afternoon, Scarlett was showing off her remarkably trim physique.

She credits breastfeeding with helping her to get back into shape and was recently seen enjoying a hike in Los Angeles.

Scarlett told Barbara Walters in an annual special that aired in December: ‘It’s the best way to get back in shape. [I do] the whole bit. I’m nursing and I love it.’

 

Hip: The pair looked effortlessly cool, both dressed in black shades while Rose was in pink
