The attack happened in the Kilmakevit Square area of Cullybackey in the early hours of Thursday.
The 12-year-old boy, who was asleep in bed, was hit in the face by the brick after it was thrown through his bedroom window shortly before 1.30am.
He sustained swelling above his eye and was left badly shaken by the ordeal.
His mother, who was also in the house at the time, was not injured.
She told UTV she has no idea why they were targeted and would appeal to those responsible to leave her and her family alone.
A number of other windows in the house were also smashed during the incident.
Ballymena councillor Declan O'Loan said the attack was "disgraceful".
The SDLP representative said: "This was a disgraceful incident and a very traumatic one for the family, and I extend my sympathy to them.
"The young boy could have been even more seriously injured.
"I have little doubt that there will be clear leads for the police to use in their investigation and I hope that those responsible will be brought to book quickly.
"I urge anyone with information to give it to the PSNI at once."
Police are working to establish a motive and have appealed for anyone who can help to contact them on 0845 600 8000.
