My 7 month old daughter frequently screams / cries out in her sleep and this usually occurs within 2 hours on putting her to bed. She has a normal routine of bath, bottle and goes to sleep by herself. What happens next is she starts to scream out very loudly with her eyes closed, writhing around, hunching her stomach and always with a fast heartbeat. We normally try and reassure her by patting her, talking to her and on extreme cases have to pick her up. After a while she will calm down but this can happen from once an evening to 3-4 times within this period. Would anyone know why this is case or have any suggestions as to help her? Thanks in advance
