Help - Daughter back with partner who kicked her out when she was 30 weeks pregnant - how to move forward??

Thanks to everyone for your comments, they have been really appreciated and helped me keep calm, for a while at least.
Unfortunately, my fears were realised a couple of weeks before my daughter’s due date when her partner asked her to leave again. No explanation given but she has since learned from a mutual friend that it was so he could have some friends over.
A week later, DD went into labour. She called her ‘partner’ to let him know and he came up for the birth but told her during the call that he wouldn’t be staying with her and the baby at the birthing centre after (they’d been offered a room for 3 nights). He left two hours after the baby arrived. He then visited for 3 hours the following day and hasn’t been back since as he, apparently, has a cold and doesn’t want to spread germs. The baby is now 10 days old. I don’t think I can express how angry and disgusted I am at his behaviour.
My daughter is doing a fantastic job at keeping positive and caring for her beautiful baby but every so often her bravery slips and I can see that she is devastated not just for herself but for her baby who deserves so much more (as does she).
I’m not sure where she goes from here but I’m hoping against hope that she isn’t even considering returning to live with him. I’ve tried not to say much about him but failed miserably on a couple of occasions.
Meanwhile, I’m exhausted helping with nighttimes while being back at work this week. Fortunately I have a very understanding boss who’s letting me work reduced hours for now.
He may or may not want to visit his baby at some point but, right now, I do not want him setting foot in my house. I guess I’ll have to tho for the baby’s sake. I’m too tired and wrung out to think straight right now so any words of support or advice would be really appreciated.
Thanks again to everyone who has taken the time to comment so far.

Dancinghorses you are doing great, tho due to your tiredness you are probably doubting this! Your concern and support for your daughter is just what’s needed atm, although I can see it’s taking its toll on you. Hang in there.

Your thoughts re your daughter’s ex are justified, he hasn’t behaved well, and the effect this has had on your daughter must hurt a great deal. She may, given a little time, be seeing all this for herself and be less inclined to be as involved with him. Yes he’s still the baby’s father, time will tell if he’s mature and responsible enough to step up.

Congratulations on your new grandchild, grab a nap whenever you can, it’ll get easier - not that that helps you a lot right now!
Good luck

Thank you for your kind words @denbylover. My youngest is only 11 but I’d forgotten how tiring the newborn phase is! You’re right, it does get easier and I just keep reminding myself of that. We’re taking each day as it comes at the moment and enjoying the small things like making the most of new born baby cuddles.
