DS is nearly 4. He has hiccups. A lot. He didn't used to up to a couple of weeks ago.
Am I being ridiculously PFB/hypochondriac/borderline-Munchausen-by-proxy and overthinking it, are sudden onset recurrent hiccups a known phase of a late-3yo, or have I inadvertently exposed him to some bizarre tropical disease that manifests itself in hiccups?
