Sleeping babies

Okay y'all help me calm down lol so its 3:41 am where I am and my 7 month old woke up at 2 for his bottle well apparently he has some gas pains bc he would fall asleep on either me or my husband but wake as soon as we laid him in his crib. Well he fell asleep on his belly and now I'm sitting in his room listening to him breath and have to be up at 6:45 to get ready for work. Will he be fine?? Always been a back sleeper also.
