"My shape is getting better and better after birth," boasted Caroline Berg Eriksen, who blogs under the name "Fotballfrue" (Footballer's Wife), as she posted a post-gym picture displaying her rippling stomach muscles on Instagram.
"Yes, of course I'm proud!" she wrote on her blog, defending her position to post yet another picture.
When Eriksen posted her first post-birth photo at the end of November, she was sharply criticised by Norwegian bloggers, with Suzanne Aabel attacking her in Dagbladet newspaper.
"In my eyes, this picture is wildly provocative," Aabel wrote. "Not just because I'm the chubby girl who's envious of her petite figure, but because I began to despise my own body when I was about twelve."
