Hello, my toddler (2.5yrs) learnt how to make herself burp a few months ago, and will sometimes do it over and over again in a way that seems compulsive. She's been a bit poorly this week with a cold and cough, which has been sometimes waking her up at night. Just now she was doing the burping thing several times between coughs as if trying to make herself feel better somehow. It all just seems a bit weird, so was wondering if it sounds familiar to anyone at all?
