Help! Any products that helped survive raising a newborn on your own?

I am due on Halloween and we have recently found out that my SO is going to have to work hours away and will only be able to come home during the weekends. He will be able to take a week off initially to help with the baby , and there's a possibility my mother will come stay for a week, but after that it seems like I will mostly be on my own with the baby (other than little check ins by my MIL). I'm a FTM and scared of messing up, and I feel very unprepared since this was an unexpected development. Any moms out there have any tips/products to survive those first few months? I will be breastfeeding and registered for a k'tan carrier since I won't have anyone helping me put on a wrap. Thanks for any answers in advance!
