My mum has had my daughter quite alot the last 15 months, my mum is 48 and my daughter 8. She stays there as me & my partner both work shifts and to have a nanny we are looking at around £1000 a month or loosing a bedroom for an au pair which isnt an option.
She has her own bedroom (made the spare hers, think girly pictures, her own bedding, fluffy pink rug and toys etc)
My daughter goes to my mums per month:
4 times at 7.30pm & goes to bed at 8pm, I then collect at 7.30am.
4 times at 5.30pm, mum does her tea & she goes to bed at 8pm.
1 fulll weekend from 5.30pm Friday - 7.30am Monday morning.
This weekend absolutley knackers my mum and thus she has given me 'her notice' which is up June 2019. My mum still works 40-45 hours a week although my dad doesnt so is generally around :)
I pay my mum £250ish a month & there is no way on gods earth she would have done it age 2. I was 19 when my daughter was two & i was absolutley exhusted, you cant take your eyes off them, and the noise? lord the noise they make, never mind the mess, its tiring!
I think your daughter is very lucky to have you help on a Friday & she should not decide to quit her job and seek further education presuming you will be the childcare, my mum offered to do it for us & i offered to pay, but it is now too much for my mum which i understand and although i am heartbroken i will be taking around a £18000 pay cut, loose my current career & its unlikely that we will be able to buy a bigger house in the time frame we wanted (not that i will/have voiced this too my mum) it is 100% my mums right to say that she doesnt want to look after her anymore, at the end of the day she is my daughter & my responsibilty & i wouldnt make her feel guilty about it.
I hope your daughter understands that when your a mum you sometimes have to do things a little differently and sometimes unfortuanly that means putting things on hold untill your children are older. I think your daughter needs to speak to the university about funds for childcare as you do get loans/bursarys for the kind of thing etc. Which really, she should have done before leaving her job & deciding shes going.
Sorry for my long post OP! Hope it is of some help xx
