A Canadian father-of-two has sparked worldwide outrage after revealing that he has a favourite child.

Buzz Bishop, a blogger and radio personality, openly admitted to liking his five-year-old son Zacharie more than his two-year-old Charlie in a post published on his blog.

"I love both my kids, but I like one better," he wrote.

"Yes, I have a favourite son and I'm not ashamed to admit it. I'm guessing you could look deep in the mirror and admit you have a favourite too."

Bishop went on to qualify his disclosure by claiming that he was unable to relate to his children while they were in their early years.

"I'm not a dad that necessarily did well with the early couple of years," he told Metro. "I wait until the kid can actually do something.

"I admit it, my oldest son is my favorite because he can do more things. To me, he's more fun," he continued. 'I don't love either of my sons any more than the other, but I do like them differently. I'd be willing to bet you're the same."

His bold statements, however, did not go down well with worried parents who have accused him of potentially causing serious psychological harm to his children.

One reader wrote: "I do have a favourite child. She is, however, my only child so I am allowed to admit that without causing serious psychological harm to any other children. This man is a terrible father to admit something so entirely detrimental in such a public way. I only hope his younger son gets the therapy he is going to need."

Another said: "It is probably human nature to have a favourite; what is very wrong is to even say which it is never mind write it down for all the world (and his children) to read. The whole column sounds selfish, self-indulgent and attention-seeking. A man who hasn't matured enough to make a good parent. I wonder which parent is the favourite of his sons"

Bishop has revealed that he now plans to get to know his youngest a little better.

"I do write brashly but I honestly didn't think it was going to be 'you're the worst parent in the world'," said Bishop. "I thought there was going to be a lot of meek, 'I feel that way too,'" he said.

"I've gone out and expressed a preference - maybe it's time for me to check that and balance things."
