So this is the second night in a past 3 that I wake up to check on my 14week old son and he is face down in his crib ... I put him back on his back but he can now obviously flip from back to tummy even though I haven't watched him do it ... As if I didn't get sleep already , now I'm scared he is going to suffocate himself... He likes to burrow his face in my arms when napping and sure enough he had his nose and mouth directly on the mattress... Anyone going thru same that can share some knowledge that will relieve my anxiety ... Thanks
