Can babies have bad dreams.Ivy will be peacefully asleep and she will start to do little sleep giggles (very cute!) But then all of a sudden she will SCREAM! Like proper big screams that she never does when shes awake I always pick her up and cuddle her and she stops screaming then she will wake and settle back to sleep straight away. Is it possible for her to know about bad dreams and stuff that early or is it something else?
