Hey OP.
I used to work in a prison. I would be very very very surprised if she got life even though the sentencing guidelines will say she could get up to that. She will be more likely to get a few years, I've seen sentences for drug offences range from a suspended sentence to 12 years (but it's men who tend to bet higher sentencing, I've seen women who were lead role get a max of 6). Do you know what role they are trying to charge her with?
But she would only do half of what she is sentenced to.
Womens prisons facilitate mums. They often do days out, which then lead up to weekends out so that the relationship with children can be maintained. I knew of a girl who eventually used to do Friday-Tuesday on child leave, and then only had to spend Tuesday evening - Friday in the jail.
Womens prisons are more like holiday camps (although very rubbish ones). They tend to live in 'houses' which house around 15-20 prisoners. They have access to a communal kitchen, washing machine, tumble dryer and living room.
If you look at HMP Styal on Google images you will see the layout, it's literally big houses. And they have (believe it or not), a gym, a library, a salon, gardens ect. She will get a job and get paid each week (around £15 which she can then spend on phone credit / snacks, they even get Avon in styal).
Yes it will be shit for her, but she will be ok. It will be more shit for the ones left picking up the pieces, like you and your mum.
Is she taking a bag with her for sentencing? Do you want me to write a list of what she should take and what is and isn't allowed?
