Do I have to report the household expenses paid by my mom as income on my income tax return?

My mom is her 80s and has moved into my home and live with us (my wife, my toddler son and me).  She pays 1/3 of all utility bills (water, sewer, electricity, gas and cable/internet) and 1/3 of property tax.  Otherwise she does not pay rent or any mortgage principle/interest/home insurance related expenses.    Do I need to report what she has paid as described above as income on our (my wife and I) income tax return?
