Thank you ladies! My mom said the same. To just watch for constant crying and overly sleepy. He's gotten better as they days gone on. No vomiting or eye dilation it's not harder than usual to wake him and he's smiling more like usual. I'm first time mom so any reassurance is welcomed. Again thanks
I really doubt that he was able to bump his head hard enough to cause damage. My 6 mos was dropped by her sister from a level approximate to that of a dining chair and she landed on her head. While she was pretty cranky for awhile (and who wouldn't be with a headache) she was perfectly fine. I know the signs of a concussion and watched for them, never took her to the doc.
It really boils down to what YOU are comfortable with. If he's not vomiting, his eyes aren't dialating funny/slowly/differently from each other, he's not overly hard to rouse from sleep...then I'd say it's safe to assume he's ok.
I doubt anything is wrong. Babies are pretty resiliant and at 3 months he's not going to have a lot of force to push off with and smack his head.
