Sore throat in 21 month old?

Ella

My 21 month old daughter has been randomly once in awhile just cough and hold her throat like 3 times today and then stops and goes about her business. At first i thought she was faking because she fake coughs alot but shes never touched her throat when she's coughed but then just now i gave her a hug and she did the same thing and then walked away, she ate her oatmeal fine and drank all her milk but im wondering if shes coming down with a sore throat. I hope she's not because im due for an induction with my 2nd next Friday and her getting sick would be awful.

Can i make her warm water with honey at her age? Anything i can do for a sore throat for her other than popsicles since I've got that already
