I had this experience before. When my baby accidentally injured his head, he was crying uncontrollably. Even when I carried him, tried swinging left right, bouncing softly up down, patting him but he just cannot stop. Then my Mil took over, hugged him tightly and he stopped crying. I wasn’t certain if it was because my mil felt very motherly and calm, the way she carries the baby made him feels very secured and the singing soothed him. But from then onwards I started to observe my tone, the way I carry and how I console my baby. I think baby could feel if we were anxious, panicked or upset. So when he cries, I tried to be as calm, carried him in a way I feel im in control and empowered. Cause I’m the mother after all.
Anyway, some also said babies cry the loudest when they are with their mothers. Go check it out. Hehe
Don’t worry so much, eventually they will still be the closest to you.
Cheers
