Hi Nazza, how did u solve this issue in the end? My baby is facing the same problem now. Got an antiseptic cream from the gp.
Did baby cry? What activity did baby do that had his toe nail side swollen? Try apply Aloe Vera Gel see if it gets better?
Scared it will turn to infection. Bring to PD instead. They might have something that is suitable for your baby
You can soak in epsom salt and they got better maybe try that!
