DD 3yrs has been constantly sniffing for the last few days and it's driving me crazy! She doesn't have a runny nose, and there doesn't seem to be anything there to blow. She's not going to get how to blow her nose yet, have tried to teach her.
She does have slightly stickier than usual eyes but not red.
Hay fever? Is there anything I can do about it before it drives me round the twist?
Thanks for any insight.
