She only noticed the design flaw after dressing her baby boy in the outfit – which was supposed to be cute.
Anna Armstrong bought a two-pack of pajamas from Sainsbury’s when she was shopping.
Both sets of nightwear, one yellow and one blue, featured an adorable lion motif in which Anna dressed her son Raphael.

But after dressing the six-month-old baby in the new clothes, the mother noticed something very mean on the front.
She said: “I dressed him and I was mortified to see a phallic space right away. I sent the photos to my fiance, we found it hysterical.
“Is it just our dirty minds or are the designers at TU for Sainsbury’s having fun?” “
Anna added: “No wonder they’re on sale! My friend bought the same outfit and didn’t notice it until her husband pointed out to her.
“Now there are so many babies in those naughty pajamas. I find it absolutely hilarious. “
But rather than throwing on the pajamas, Poole’s Anna saw the fun side and shared it on Facebook instead.
She wrote: “Did anyone else get this outfit from Sainsbury’s for her little one?” “
Anna concluded: “I didn’t notice it until I dressed it this morning, but now I can see why it was in the sale. Whoops. “
The pajamas are proving to be a hit with parents as they are currently sold out on Sainsbury’s website, reports the Daily Star.
In fact, some parents even left five star reviews.
One wrote: “Ahhhh, the blue top really made me laugh, thanks for the Sainsbury’s laugh! “
