Barrett Walsh – the 2-year-old allegedly killed by his Lindsay Clancy-obsessed mother – was remembered as a “rambunctious” tot who loved playing games with his siblings, according to his heartbreaking obituary.

Walsh – affectionately known as “Bear” – was found dead on Sept. 1 after his mom, Corie Walsh, allegedly hanged him from the rafters in the basement of the family’s Illinois home.

The tragic toddler “will always be remembered as a joyful, funny, entertaining, rambunctious 2-year-old who loved singing and dancing to Super Simple Songs and Miss Rachel,” his recently published obituary reads.

He also enjoyed “learning his colors with Pingfong and Hogi, kicking a soccer ball with his friends and counting out loud to 5 Little Duckies.”

Little Barrett was a “cherished little brother” to Grady and Anna and a “caring big brother” to a baby boy.

He was an active kid who already had a positive outlook on life, his obit says.

“He loved animals, bedtime stories, doing the good-bye dance with joyous perfection, feeding Oscar too many treats and really enjoyed playing his favorite game Ready, Set, Go with Grady and Anna.”

Corie Walsh, 40, was charged with first-degree murder after Barrett’s two older siblings found him with a rope around his neck in the basement of their home in Frankfort, according to court docs obtained by The Post.

A frantic neighbor called 911 and tried fruitlessly to perform CPR on the youngster, who didn’t have a pulse and was cold to the touch. He was pronounced dead at the scene.

An autopsy later confirmed that Barrett died of “asphyxia due to ligature compression of the neck,” according to court records.

His mom — whom cops had discovered fully clothed, soaking in a bathtub full of bloodied water at the house – tried to take her own life by slashing her wrists and thighs with a knife before first responders arrived.

She was reportedly so out of it that she believed she had killed all four of her children. 

Corie was texting her friends about the Lindsay Clancy trial jury deliberations, which were happening mere hours before Barrett was killed. 

The texts were “confusing” and “out of character,” saying she believed that Clancy’s husband killed the children – not their mother, according to court documents obtained by The Post.
