Any advice?

Chesh • Mummy to Theodore and Daniel

Toddler split his nail, was healing nicely, then he caught it again the other day and now it looks worse. Pictures aren't great, but most of the nail has gone purple, with a very dark patch directly under the split (it looks like it's just bruising under the nail, but was hoping there was something I could do to help speed up the healing process). Thank you in advance!
