Have you tried a swaddle blanket? My son loved being in a swing and in the highchair. Is she crying because of hunger? Is she on formula? One time my son cried all night I finally discovered it was his clothing.
Like margypops said are you mom or dad? Maybe she needs to be held more.
There is always a reason is, are you mom or Dad? does she only cry at home, can you enlarge on the details so we may help you further ,how old is the child has she siblings, ?
