Is there a disadvantage if the parents try to be very very silent when the baby is sleeping? For example making sure that TV and mobiles are muted, no dish or clothes washing is taking place and all conversations are being very silent even if they take place very far from the baby's room?
I'm afraid that if the parents do this for a long time (e.g until baby is 2 years old) afterwards the child will be very easily woken up by noises. Does this theory hold?
