children’s movie in the autum season setting ( a brother nd sister )

i saw this movie years ago . There was this boy and his sister ( around 12-14 ) . they lived in the countryside with their dad and stepmother . I think there were spirits involved maybe . Their stepmother wanted to give birth to her baby in a hospital but the boy and girl wanted her to do that in their home where they were living at the moment . This movie had cold autumnal vibes to it .
