Third baby feeling anxious.

I’m 36w3d. I have a 10 year old daughter and 13 month old son. I’m completely terrified about this birth. I’m nervous about finding the time to breastfeed and pump for storage all while keeping tabs on my very active toddler. I’m nervous about going into labor at work, or at home with my kids and no other adult. There’s just a couple of examples. I know it’s normal to worry but all this worrying has what little sleep I am getting between rolling over and getting up to pee filled with nightmares involving my kiddos. Anyone else’s first trimester nightmares return? My mind can’t rest.
