Is it ok to lay baby on chest for naps

Is it ok to lay 1.5 month old tummy down on our chest while we lay 45 degree up? For short naps and i wont be sleeping. Will it hinder their breathing since its kind of pressing on their chest? As my baby will wakeup whenever i put him down, this is the only way to make him nap a little longer, atleast till we make it to the next feeding time 😂🥵 #firsttimemom
