Most little kids are thrilled when the school day is over, but little Louis Bardo Bullock doesn’t appear to be one of them!

Sandra Bullock’s adorable boy refused to crack a smile as his devoted mom picked him up from preschool on Thursday – and Breaking Celebrity News has the photos.

Clearly a multi-tasking woman, the Academy Award winning actress held onto her son with one hand and used the other to clutch onto her cell phone and what looked like Louis’ school bag.

After four years in the adoption process, Sandra and her now ex-husband, Jesse James, took little Louis home in early 2010, and after the couple split, Sandra finalized the adoption as a single parent.

As Breaking Celebrity News previously reported, Louis does occasionally manage to smile for the cameras!

The two-year-old appeared to be roaring with laughter as his 47-year-old mom picked him up from preschool on another occasion recently.
