Emergency crews responded around 1:45 a.m. to a home in the 25000 block of Fountain Bleau near Boudreaux Estates.
According to the sheriff's office, the 27-year-old mother was bathing her 4-year-old and 1-year-old boys when she walked away. It's not clear how long she was gone.
When she returned, she found the 4-year-old face down.
CPR was started on the child, who was rushed to Tomball Regional Hospital. He was pronounced dead a short time later.
Officials say the boy may have had cerebral palsy, along with other medical conditions.
An autopsy will help to determine what happened.
Homicide was called out to the scene, which investigators say is standard protocol in these types of situations.
A 77-year-old man also lives at the home.
Authorities say the mother is distraught. They plan to interview her to find out why she walked away and for how long.
