Sleep Apnea Treatment

I think my son may have sleep apnea. He stops breathing sometime, just for a few seconds, and he gasps for air. My husband has sleep apnea and I know what it is like. I asked my son’s doctor about it and he said it might just be reflux and switched his formula. I would just like to know it anyone else has a child this small with sleep apnea and it this sounds like what might baby might be experiencing.
