My 5 month old flipped over and fell off the bed. Doesn't seem like it's anything serious but he's been waking up every hour at night since. Could this be night terrors or should I be seeing a doctor to check for a head fracture?

Oh dear, I think it's always better to check with the doctor first, just to be sure and rule out that baby is not injured in any way. Sometimes injuries that cannot be seen are scarier than those that are visible. Follow your instincts, if you feel uncomfortable with the severity of your child's fall — you think he must have gotten hurt — or if your child is acting irritable or confused, take him to the doctor to get checked out. Till then, keep observing baby for any anomalies especially if he fell and hit his head.
