The internet has slammed a new father for falling asleep with his daughter in his arms.

Published to Reddit's r/AmITheA**hole forum, a dad under the anonymous username u/ilovecaptainmorgan shared his story in order to receive feedback from the "AITA" community.

The original poster (OP) began his story by explaining that he and his wife recently welcomed a baby girl. He said that having a very young child was "just straight up hell," adding that he works long hours and has trouble sleeping at night due to his daughter's sleep cycle.

"On Sunday morning, my wife went out with her friends for the day and I was watching our daughter," OP began. "I had no energy and when my daughter fell asleep in my arms while I was on the couch I did too. I woke up to my wife yelling at me with my daughter in her arms. She was going absolutely ballistic and telling me how irresponsible I was for sleeping with my daughters in my arms like that. I really think it isn't an issue but she clearly does."

Newsweek reached out to u/ilovecaptainmorgan for comment.

Co-sleeping is defined as when parents sleep with their babies on the same surface. This can be very dangerous as co-sleeping comes with an increased risk of sudden unexpected death in infancy (SUDI) including sudden infant death syndrome (SIDS) and fatal sleeping accidents.

Adult beds have many products that can pose a risk to an infant's health including the kind of mattress, blankets or pillows, which could cause an infant to suffocate. Newborns could also become trapped between the headboard and the mattress, according to kidshealth.org.

To prevent unexpected co-sleeping accidents, have your baby sleep on their back at night on a firm surface in a safety-approved crib, according to the CDC. Keep soft bedding including blankets, pillows, toys and bumper pads out of the sleeping area. It is okay that a child sleeps in your room, not in your bed.

"[You're the a**hole]- I'm a RN at a large metropolitan Children's hospital. We see horrific cases of babies falling asleep with parents so often. When babies fall asleep on their parents chest or in their arms, they can become trapped between the parent and the sofa, chair or bed. Often they are unable to breathe causing death or a Traumatic Brain Injury (TBI). With a TBI the once vivacious baby with an unlimited future ahead ceases to exist. In its place is a baby/child/adult that is bed/wheelchair bound, have to be fed through a tube, unable to walk, talk or toilet by themselves. Ever," u/titancrisp warned, receiving the top comment of over 12,000 upvotes.

"OP-you are [not the a**hole] for sleeping when the baby sleeps. In fact, I do recommend it. Just be safe and smart about it. Put the baby in a safe place-crib to blanket on the floor. Remember SAFE sleep. Put baby to sleep on their back, on a firm surface such as a crib mattress, alone and no extra soft toys, pillows or blankets," the commenter continued.

"Soft [you're the a**hole]. It's against several medical guidelines to co-sleep with a child under 1 year as you can suffocate the baby if you shift your weight or roll over, she could slip out of your arms and fall, and just the general risk of essentially leaving a child unattended while you're unconscious. I know you didn't mean any harm but I totally understand why your wife was upset. Next time put the baby in the crib," u/KrankenFluffer said.

"[You're the a**hole]. You're tired, I get it. But that was dangerous and your wife's anger isn't out of place, and your attitude is what makes you [not the a**hole]. It IS an issue and you need to take it seriously," u/Ksanral commented.
