She might have a hay-fever type allergy if it worsens outside? But we have 6 kids and there's been constant coughing in our house since before Christmas, it's relentless 🤦♀️
I’ve taken my boy to have coughs checked out a few times. Sound like it’s very similar to your daughter. GP said a viral cough can take 6-8 weeks to clear x
Honestly my daughter has the same thing, but she was vomiting a lot, and after a lot of back and forth with the doctors and pushing to get seen by the hospital, we got told she’ll likely grow out of it but the NHS website says a cough over 3 weeks is a concern to check up. I would go to the doctors and ask about it, yours may be better than mine have been x
