kid!fic where merlin falls and hits his head, so their child calls arthur at work to get help

[rainbowpoopies]

Hey! I'm looking for a fic i read years ago. Might be a long shot, but it was a short modern!AU where merlin and arthur have a young kid and one day merlin i think trips on one of the kids toys and hit his head. The kid has to call arthur at work, obviously panicked. I believe the summary of the fic was just the dialogue of arthur first answering the phone?

Sorry for the vague description, ive been searching through my old fics i've read and can't seem to find it.

thanks!
