My LG has had a cold on and off since October (picking up every single bug from nursery). At first I was reluctant to go out as you said in case it made it worse but imagine if I hadn’t gone out all this time 😅 as long she is feeling well in herself and isn’t running a fever or anything I would say just carry on as usual.
Cough , nose running -yes. Temperature- no
I would carry on my normal life if she's her normal self.
