Baby's first swim?!

Bristol Palin took her adorable daughter, Sailor Grace, for a dip in a pool earlier today—and she made sure to document the daytime outing.

The 25-year-old was seen wearing a bandeau-style bikini as she snuggled up to her almost three-month-old baby girl.

Palin captioned the adorable mother-daughter photo, "my heart," and by the looks of it, little Sailor appeared to be enjoying her day in the pool.

Sailor was dressed in a bathing suit and protected from the sun in a white hat while her proud mama gazed lovingly at her.
