we daughter rely on this mobile to fall asleep every night and at each nap time . even when she be fussy and fight sleep , the mobile almost always draw she in even when I expect she to know better than to fall for its mesmerizing power . and when she be playful and awake , she happily watch it , kick she leg , until she burn off she excess energy and doze off . it be almost like a friend to she , comforting she when she be leave alone to sleep . this past weekend we be away from home and be without the mobile for one of the first time in she life -lrb- she be 7 mo . -rrb- . it take hour to get she to sleep , despite be obviously exhaust and despite have a different soothing toy there with she . it be so obvious she be look for it whenever we try to lay she down . the night we get home , she be overtired but seem so relieved to be reunite with she mobile . she doze off without a peep . I guess the only downside be that obviously she might be too reliant on it , but if it mean have a baby go down easily on a regular basis , I be okay with that .
