Alright, my DS who is 12 days old does this weird thing when he sleeps

......he seems to be fine and then it sounds like he stops breathing, just for a second, but then takes a few gasps to catch his breath and is fine again. He does this numerous times....and I am wondering if this is normal, or if I should contact the doctor about him maybe having sleep apnea? I have a humidifier in his room constantly, which his doctor recommended at his first check up for the first few months....maybe it is too humid? Any suggestions would be greatly appreciated.
