Morning Damien, you're right it's the mother's hair, I was shooting over her shoulder. I hadn't intended to remove it because it 'fit' with the context of the shot whereas the foot is just discomforting.
I don't have another shot with that side of the rug toe-free but I do have one where I re-framed the shot to block dad's foot with mum's head (baby's expression is better in this one)....perhaps that's a better solution that trying to repair the rug?
