What is this?

Anita • Mama to Theo and Hailey 💙 💗

My baby is nearly 4 months old and has this red bump at the side of her toe? What could it be? I asked my nurse but she didn't seem concerned as long as its not hot to the touch and it isn't? I'm going to make an appointment with my GP too, does it look like an ingrown toenail? Baby doesn't seem to be bothered by it.

TIA
