It is at that age. My son didn’t fall out of cart but at that age he ran straight into the edge of our dining table and had the same swollen indented mark on his forehead. I immediately called 911 and his Pediatrican and they told me it was normal because their frontal and temporal lobes are still soft it won’t necessarily crack it’ll just push it in like putty and it will come back
@mommy121618 oh yeah, the sound was frightening for sure, so it happened yesterday and he's been normal all day today? I would think he's fine but of course that's your call depending on what makes you feel best. If u don't want to take him in I would at least call the advice nurse for some reassurance and see what she advises u to Do 😕
