Indonesia’s chain-smoking baby has kicked the habit.

That’s the good news. The bad news is that he’s a junk-food junkie, packing on some serious pounds!

Aldi Rizal made world headlines three years ago, when pictures and video emerged, showing him as an infant, puffing away in a 40-cig daily habit.

Now 5, the not-so-little Aldi has traded one unhealthy habit in for another, according to The Sun newspaper in London.

He’s up to four stones – 56 pounds – on an unhealthy diet of junk food and condensed milk.

“He eats a lot,” his 28-year-old mom Dians said. “ With so many people in the house it’s hard to stop him getting food.”

Loved ones are now trying, again, to steer Aldi the right direction, by feeding him a steady diet of fruit and vegetables.
