I'm not a professional, but unless your daughter and her partner have additional needs I'd have said th a t you are 'loving too much'! Whilst I understand your being so physically involved for the first few days, I'd be very uncomfortable your spending the day, all day, every day.
You are not this baby's parent, the baby has 2 parents. I think most of us have had sleepless nights for weeks at a time when our children were babies, it's part and parcel of being a parent. To me, you have confused your role and however well intentioned, you have now started to take over as mother for this baby, during the period when they should be bonding.
Please be a gran, offer to help, but step back, get them to talk to their health visitor or GP as others have. Suggested, the all night crying may be any number of reasons, let the professionals take over.
And maybe there are other things that you could do to fill that void that you must feel now that your daughter has moved on to the next stage of her life.
I've got another 'keen'... Ouch!
