Mine doesn't. He seems to be able to sleep through pretty much anything. When/if he does wake up, he just looks at you like you're bothering him. He doesn't get scared or spooked.
I'm just wondering if this is normal or if I should possibily have his hearing checked. He passed the hearing screening at the hospital, but I can't help thinking something may be going on.
Re: does your 4 month old spook easily?
Mine sleep through most noises and don't get scared if they are woken up. I think it's a good thing! Does he get startled if theres a loud noise while he's awake? I think that would be more of an indicator of any hearing problem. Sounds likey you have been blessed with a good sleeper
