But Calista Flockhart and Harrison Ford made sure to enjoy a spot of couple time as they cheered on the youngster from the sidelines at a football game in Brentwood, California, on Saturday.
The pair looked into each other's eyes as they leaned in for a tender kiss.
Both the actors had opted for baseball caps to shield the autumn sun from their eyes, with look casual in denim jeans, Harrison with a lightweight beige jacket and Callista with a khaki coat.
Sipping from a coffee cup and chatting with other mothers in attendance, it was clear the 47-year-old star only had eyes for the two men in her life.
Liam looked immaculately turned out in his sports kit, with his yellow and sky blue T-shirt tucked into his shorts, and he seemed thrilled to have his parents in attendance at the game.
