Hi, my 17 month old fell on the back of her head while trying to climb up a ladder. It was about 2 steps up when she fell on her butt first & then her head. This was yesterday, however today I noticed a soft spot on her head, not necassadily where she hit it. I instantly panicked. Her pupils are fine, no vomiting, no restlessness. She is completely normal as far as I can tell. Should I take her to ER?
