This hilarious video captures a new mother's shocked reaction when she is told she has just given birth after forgetting the ordeal while still high on medication from the labour.
Tisha Heffron was filmed by husband James just hours after giving birth to their second son, Clay, at Marine Corps Base Camp Pendleton, San Diego, California, on Monday morning.
Still feeling the effects of the morphine, Tisha adamantly denies having a second child before asking her husband "whose baby" is in the room.
She also asks him whether he is her brother and has to be told the baby did not come out of her belly button.
Mr Heffron said: "I was torn between trying not to laugh and making sure Tisha didn't stand up. Nurses had told her not to leave bed and get as much sleep as possible.
"Her first reaction was to go for a walk but I couldn't let that happen. This went on for at least ten minutes before she fell asleep again."
At one point he tells his drowsy wife: "You gave birth to Clay over there." She responds angrily: "No! I gave birth to Jackson," referring to their 15-month-old son.
As she works through a confused train of thought, Tisha closes her eyes and asks her husband: "Can you see me?," before questioning whether he is her mother.
When she is told she "pushed out a kid", the new mother asks: "Out of my bellybutton?"
Her husband then explains how she gave birth and she lifts her hospital gown to check he is telling the truth.
Mr Heffron said once she woke up from her 'drug induced hibernation' she was "fully cogent."
"Straight away she remembered Clay and the whole birth process,' he added. 'That was a relief."
