Hilary Duff and her son Luca ran errands in the valley on Tuesday afternoon, and it looks like someone was ready for a nap! Er, make that two people?

Hil's adorable 7-month-old was completely passed out in her arms, and the night before she tweeted, "Uh huh! Ya ya ya! In bed before 10 pm!! Someone's going to wake up fresh!!!!"

Hilary celebrated her 25th birthday on September 28, and after receiving a boatload of presents and going out to dinner and drinks, she and hubby Mike Comrie took a mini vacay to Santa Barbara last weekend, returning to Los Angeles just in time to catch Florence and the Machine at the Hollywood Bowl on Sunday night. She's one busy mama!
