Throw up/Spit up while sleeping

Ki

Ladies,

Its 2am. Finished my son's last feed about an hour and 40 minutes ago, hes now fast asleep in my arms. Reason hes not in hes bassinet is because after hes last feed we did burp and all that I layed him in hes bassinet and I climbed into bed, he fussed for about 20 minutes and I kept checking on him only to find he had thrown up/spit up alot. It drolled to hes ear and he was laying in it (blissfully) wasnt crying..moaning..nothing

Now I'm freaking out... what if I feel asleep and didnt check on him (sometimes he fusses and dozes off to sleep by himself) and he chocked on that! It was alot that came up :( I cant sleep now (hes been out for about 30 minutes now)

He sleeps on hes back (if interested) but any advice from moms on this?? I am a ftm so just worried why he brought up so much of hes feed and what happens if he does this while we are all sleeping:( ... help a worried mind here ... need real advice .. first time he has done this, he is 5 weeks.
