Postpartum stiffness, especially in the neck and shoulders, is often caused by repetitive postures during feeding and carrying. Gentle relief can be found through exercises like chin tucks, ear-to-shoulder stretches, shoulder rolls, and wall stretches. Using a foam roller for thoracic extension can also help open up the chest and correct forward-shoulder posture. If you experience clicking joints, this is often normal, but if accompanied by pain, seek a consultation with a sports physiotherapist to rule out diastasis recti or other musculoskeletal issues.
