Feeling overwhelmed

Im currently trying to bouy up and support my dd who is returning to work next week after 8 months mat leave.
I'm having the baby 3 days and her partners family 1 (which she's not happy with at all, but can't be resolved)
Baby has a a few health issues, plus lockdown and this new way of living has impacted mat leave for them.
I see her prob 4 days a week at the mo, try to get into a routine with the baby etc but also because we enjoy spending time together!
She's struggling so much with the thought of being back in work, she's still breastfeeding too.
She's crying most days that I'm with her which just breaks my heart and makes me feel guilty that I will have the baby when I think it should be her as that's what she desperately wants.
We have a week now before she returns and I'm absolutely feeling sick at the thought.
She can't afford to not work, she's dropped one day.
I've actually dropped lots of hours at work so I can do the childcare and save them nursery fees so I'm not in a position to help financially, I wish I was
Her partner isn't the most supportive either either emotionally or childcare wise so my dd and the baby have a very strong bond.
I suppose my question is any suggestions to help get her thru this tough period?
I've bought a few little tokens to give to her, but now I'm thinking is this the right thing or will it make her worse
She's having thoughts that someone is going to take the baby from her or that something is going to happen to him. I realise that this is her anxiety.
