Are fathers more accident prone or careless with young children than mothers?

For instance in my family, when my niece was 7 months old, she fell out of the bed while under her father's (my own brother) care. Prior to the accident, his wife (my sister-in-law) told him several to never take his eyes off her for a second not even to pick up a wipe, to leave him on the crib, strapped stroller or hold her. My sister was in the kitchen making breakfast for the baby and she came back to the room, only to see her baby fall and cry loudly. He took his eyes off her for a second to clean up a spit-up and she rolled over fast, falling. Meanwhile my sister never had that happening to her.

They took her to the clinic and luckily nothing happened. Other cases I've heard about where an actually tragedy did happened was about a father carrying an older baby in an upright position over the shoulders with only one arm at a mall (when going up the mall's moving escalators) the baby arches backwards and falls to his/her death.

Then when the kid is an older toddler, several men do the stunt of making the kid sit on his shoulders, not realizing the risk of the kid falling too.

Generally are men more careless and accident prone with babies and small kids than women?
