Bristol Palin's son, Tripp
, is officially in the second grade!
The 25-year-old mom of two commemorated Tripp's first day of school with a precious Instagram post on Monday.
"First day of 2nd grade for my babes!! and first time I’ve seen Tripp in jeans all summer," Palin captioned a sweet pic of her standing with her 7-year-old son Tripp and brother, Trigg, who is also 7.
Palin also Instagrammed a couple new pics of her husband, Dakota Meyer, and their 8-month-old daughter Sailor Grace
In a "chunkalicious" post from Monday, Sailor Grace sits smiling in her car seat, while another sweet pic shows the baby happily seated on her father’s shoulders.
"Hit the jackpot," Palin wrote next to the daddy-daughter shot.
Aside from marking Tripp's first day of school, the Alaska native has recently been celebrating married life. She tied the knot with Meyer this past June.
