Miranda Kerr hit the jackpot with two great guys: hubby Orlando Bloom and their 10-month-old son Flynn.

"[Flynn's] crawling now. He has eight teeth!" she told Us Weekly on Monday at her Halloween party at Catch  in NYC.

So has teething turned Flynn cranky? "No, he's a very happy boy!" Kerr, 28, gushed. "[I'm] very lucky."

"[He likes] when I sing to him," she told Us, then sang, "'Be-bop-a-lula, he's my baby!' He likes that."

The first-time mom says Flynn's first holiday season is going to be "so exciting."

Her favorite part of Christmastime? "I love putting little things in the stockings!" she said. "[Also] I love to cook... I cook everything! I love cooking roasts, like roast chicken and vegetables especially over the holidays."

When it comes to gift-giving, the supermodel and her hubby, 34, are into quality over quantity. "One of the most thoughtful things [was] when Orlando and I had written all these love letters to each other. Then one year, he had them framed for me, like all the little notes!" she said. "It was very cute."

And although Kerr's career is hotter than ever, her main focus is family life with Bloom, who she married in 2010, and baby Flynn.

"My priority is to be with [Flynn]," she told Sydney's Herald Sun last month. "So I am very selective with [the jobs] I do."
