Bristol Palin’s 1-month-old is a cheeky one!

The daughter of former Alaska governor Sarah Palin Instagrammed a picture of her daughter Sailor Grace swaddled in a cozy floral blanket on Thursday, January 28. “Lookin like she’s trying not to smile!!” she wrote along with the sweet photo.

Bristol, who is also mom to 7-year-old son Tripp (with ex Levi Johnston), returned to work as a medical assistant at a dermatologist’s office in Anchorage, Alaska, on Monday after giving birth to the little girl December 23. “Back to real life today!” she posted. “I was fortunate enough to take the last month off to stay home with my babies, today marks the first time I’ve left SailorG, but I could not be more thankful she’s in the best of hands!! #igotit.”

The Dancing With the Stars alum announced she was expecting this past June, just one month after ending her engagement to U.S. Marine Dakota Meyer a week before their nuptials. Bristol has yet to confirm whether Meyer is Sailor’s father. Meyer, 27, however, claims to be the biological dad and is seeking joint custody. 

Meanwhile, babies aren’t the only thing on Bristol’s brain. The 25-year-old took to her blog Monday to slam Tina Fey’s recent impression of her mother on Saturday Night Live. 

“I’m sure many of you saw Tina Fey, who sounds nothing like my mom, do a skit based on my Mom’s endorsement of Donald Trump,” Bristol wrote. “I may be biased, but I think my mom trumps her in the looks department. (Especially for having three more kids and seven more years on Tina!)”

She continued: “I don’t know about you, but hearing her fake accent is like nails on a chalkboard for me!”
