It's on her cheeks - I've realised it's where she brings her cup up too high when she drinks and it hits her face. Don't know why it's causing the soreness but it's definitely that.
I thought to start with she'd scratched herself and have been using Sudocreme, but it's not helped. Have got her using a straw at the moment to stop the contact but it's red and sore and I don't really know what to use on it. Any suggestions would be gratefully received!
