He's getting so big!

Reese Witherspoon stepped out to run errands in Santa Monica today, and the actress had her hands full with her adorable son Tennessee. Although we haven't spotted the blonde beauty with her youngest child very much since he was born, she seems to be stepping out with him more frequently as of late and we love it!

Her little tyke must have just gotten a check-up because he's sporting Band-Aids on his thigh and big toe. Getting vaccinated is never fun!

The Southern belle seems like such a fun mom, though! The Oscar winner recently admitted that she keeps keeps her brood entertained with a little song and dance.

"I do a lot of dancing with my kids, and when I get dressed in the morning. I have a playlist. A lot of country. A lot of Top 40. My kids love Macklemore, so that," she divulged to Vanity Fair.

Little Tennessee needs to learn how to walk before he can take part in the family dance party!
