My newborn will only sleep while being held, any advice to get her to sleep in the cot?

The reason could be that your baby just wants to be held by you. Your scent, warmth, smell and heartbeat are familiar and soothing to her. You can try swaddling her to help achieve the same comforting effect. Newborns are still unable to calm themselves down. To get her to sleep on her own, try to help her learn how to soothe herself. Be patient, stay with her while you put her down for naps in the day. Stroke her face or hands and sings to her while getting her to try settling on her own. At night, put her down in her cot after she is in deep sleep. If she wakes up the moment you put her in, resist the urge to pick her up immediately. Let her adjust to the idea but do make sure to comfort her and not simply let her cry it out.
