Carrie Underwood says her toddler son thinks she's a 70-year-old whose job is doing laundry

It doesn't matter if you are a chart-topping, award-winning country superstar, singer, songwriter and fashion designer, to your kids you'll always be a 70-year-old lady doing laundry.

Carrie Underwood took to Instagram Thursday to share a snap of her 4-year-old son Isaiah's homework assignment — you know the ones where they have to answer questions about their mom.

"Soooo...apparently I’m 70 and I’m really good at doing the laundry," Underwood captioned the post, adding the shrugging and cry-laughing emojis.

Isaiah writes that he thinks his mom is 70 years old and then twice fills in comments about laundry.

My mom's job is: wash the laundry. (Or performing to crowds of thousands.)

My mom is really good at: folding laundry. (Or winning Grammys.)

There were some sweet responses as well like "My mom always says 'I love you' " and he really wants to buy her a cake.

Underwood shares two sons with her husband Mike Fisher. They welcomed their second son Jacob last January.

While Isaiah may be clueless about his mom's stardom, Jacob at least seems to appreciate his mom's melodic singing. Last year she posted an adorable and hilarious video of her and Fisher singing a lullaby to then 5-month-old Jacob. When Underwood sings, Jacob is quiet and content, but when Fisher sings, the tears flow.
