Best to consult your paeditrician...just to be sure so you can take immediate course of action or breathe a sigh of relief...I hope all is well.. take care 🙏
There are other ways you can test.. like if baby cries when the door slams/there’s a loud sound.. or whether baby responds to you talking/singing/playing.
By 3 months babies should recognise the sound...see if the baby reacts to noises or when the door is slammed if gets scared
By 3 or 4 months of age, babies are usually able to turn their heads toward a sound. You may wish to consult a pediatrician.
