She wakes up before the sun,
She cleans up everyone,
She brushes my teeth,
Washes my face,
She can cook up a meal
before I can say
My mom is a supermom!
My mom is a supermom!
She washes her hands with soap,
Before idli or before soup,
She combs my hair,
She cuts my nails,
She can get me ready
Before I can say
My mom is a supermom!
My mom is a supermom!
She tells me many good stuff,
Some easy and some tough,
wash my hands with soap after toilet,
Wash my hands with soap before I eat,
but she can do all this and more
Before I can say
My mom is a supermom!
My mom is a supermom!
