Sheryl Crow and son Wyatt
may have received thunderous applause for her performance with Miley Cyrus
at VH1's Divas Live
on Thursday, but her 2-year-old son, Wyatt, is fed up with her singing. "I want to sing to him, but right now he's like, 'Mommy, no! All done! All done!' " Crow told PEOPLE at Thursday's event
That's not to say that Wyatt doesn't appreciate good music. "He's really into kids' music and is listening to a lot of Raffi. I think he thinks if I'm singing that I'm going to work," she says.
Crow, 47, adopted Wyatt
when he was two-weeks-old, and last year the singer and her tot traded the glitz of Hollywood for a quieter life
"Everything about me has changed. My point of reference has changed. [Wyatt] is the first thing I think of in the morning and the last thing I think of at night, and it's just a lot of joy in my life," she says. "I definitely sleep a lot less."
And while most two-year-olds can barely pull up their pull-ups, Wyatt is practically ready to do laps.
"He's a great swimmer, which is crazy. He literally can swim by himself now across the pool, and he has the most wicked sense of humor. He's definitely a boys' boy. He loves trucks," gushes the happy mom, adding "Life is great. I'm loving it. [Wyatt] is just fantastic and I'm working on a record and life is just good."
