January Jones may be a single mom, but she's got a huge support system!

The Mad Men star looked comfy-casual in jeans paired with a striped sweater and white tank, she she headed to lunch with her sister and nine month old baby Xander in tow, on a sunny Saturday afternoon in LA.

But while the 34-year-old actress protected her eyes from the blaring sun in some oversized shades and tried to shield her son's face with her hand, the little guy was fully exposed to the powerful UV rays -- get that kid a hat ASAP, Jan!

We're beyond bummed out that Mad Men's final episode of the season airs tonight, but Jones will most-likely be glad to leave the fat suit behind, after shooting the show eight months pregnant, and wrapping production when her son was five months old. Will January ditch the fat suit next season?
