A picture of a US woman's hospital bill has gone viral thanks to one particular service fee: a charge for holding the baby after delivery.

In an photo posted on Reddit by said baby's father, the woman was charged for "skin-to-skin after c-sec" to the tune of US$39.95 ($64).

"During the C-section the nurse asked my wife if she would like to do skin-to-skin after the baby was born," the father wrote in the comments. "Which of course anyone would say yes too [sic]. We just noticed it in the bill today."

However, the new dad wanted to stress that their experience holding their baby was not bad, they just thought it was funny they were charged for it.
