Worried somehow sleep on bb

During newborn - 3mo (when she’s learning how to flip), I let her sleep on baby nest between my hubby and me. My hubby who is a heavy sleeper somehow subconsciously will “retreat” when he sense baby before he turns himself. Cant say that it’s all the same for all parents so best to elevate baby slightly higher when cosleeping. Go easy on the pillows and blankets as well. LO is now 19mo and sleeps all over as long as one part of her body touches someone 😊.
