Little Big Town's Trailer Stolen But Thieves Only Made Off with Kids' Stuff

Little Big Town keeps getting the shaft, but in the latest case ... at least the perps who jacked their stuff got a heavy dose of karma.

The acclaimed country band's trailer was stolen Tuesday night in Nashville, but instead of the thieves making off with a load of guitars, amps and expensive band equipment ... they got a bunch of children's gear.

Sources close to LBT tell us a police report was filed with Nashville Metro. The items in the band's trailer include 3 kids razor scooters, 3 bikes, a homemade lemonade stand, a unicorn kiddie pool with a unicorn sprinkler, pool toys, bubbles, chalk, kickballs, basketballs, baseball gloves and bats ... and some workout gear.

Probably not exactly what the criminals had in mind.

For the country band, the burglary news comes on the heels of another unfortunate situation. TMZ broke the story ... Little Big Town's 4 AMA trophies accidentally got sent to Lil Wayne.

Just call it a lil mix-up.
