Yes it can. Although, when using motion sensor pads, such as Angel Care, we recommend that the sensitivity is tested with the doll alone, where it will be situated with the baby during sleep. Lulla emits sounds of a heart beating which generates small movements. This can be detected by motion sensor pads if they are set to the highest sensitivity and the doll is situated directly on the sensor pad. However, pediatric guidelines recommend to parents to not have anything loose in the baby's sleep environment before the age of 12 months. Therefore, the Lulla doll has velcro straps and can be attached to the crib or be placed outside the crib
