Help! Brown spot on toenail. Photo.

[Spottytoe17]

I have just discovered this light brown mark on my 17m old's toenail. Has anyone else's toddler had anything similar. Is it anything to be concerned about? Thank you!

I don't think i would worry about that.
Take a picture of it today and again in a weeks time to compare. if it isn't fading or has got worse then i would contact GP or HV.
It will probably be gone next week x

Likely a bruise under the nail
If It is it won't be gone next week as it has to grow out the nail slowly. I've had one confirmed by a dermatologist for five months now and it's almost grown out
