Girls, help me! First of all, I want to say that every mom is a hero ? I'm a mom without experience I started rocking my baby on a fitness ball while he had colic, now I can't live without? and the baby won't sleep otherwise, not even on his hands or in a stroller only on a ball. Can you please tell me what to do? It's not hard for me to rock on a ball, but we can't get out anywhere for a long time. Also about the street... Always excited by any sounds, sometimes almost too much, almost shaking, it really stresses me out. Is this normal at 3 months old?
