Carrie Underwood works around her three-month-old son's schedule.

The 32-year-old singer, who gave birth to first child Isaiah Michael in February, hasn't ''taken that much time 'off' '' because she has been working on new music and her new collaboration with exercise wear line Calia over the past few months.

The 'Before He Cheats' hitmaker said: ''I really haven't taken that much time 'off' because there are always things to do. It's been really nice to be able to focus my attention on Isaiah and our family. It's been really good! But it's been really nice as well to be creative, working on music, working on Calia. Making clothing that every woman can wear and enjoy makes me feel good.''

But the blonde beauty, who is married to Nashville Predators player Mike Fisher, insists Isaiah is her number one priority and she tries to do most of her work when he is napping.

She told ''Having a baby definitely changes your routine, and I have to work around his schedule. Whenever he goes to sleep, I do the things I need to do for myself and make workouts happen when they can.''

Carrie is set to perform at the CMT Music Awards later this month.

She said: ''I'm excited to get back on stage.''
