Day to day care of the baby is my sister.
She has not reported the physical abuse to the police as there are no visible marks on her body showing that her husband has abused her. She is worried that if she report the abuses she will lose her baby as she is only on temporary UK Resident Permit and that her husband will be more violent. Moreover, if she reports to the police and no help is given to protect my sister and the baby she would be risking her safety. Her husband's mother and sibling's wife who are staying quite near them are not supportive of my sister as well and always side with her husband no mater who is in the right. Even if her husband is taken away, they might cause harm to my sister and/or the baby.
My mother will be flying over to stay with them next month to look after the baby while my sister will go back to work. Her husband does not help really help much with the domestic finance. My sister pays for most of the baby's products (food and other necessities).
