I feel the same way. My daughter will be staying with my parents. Despite my well laid out planning I know she is going to live on ice cream those three days. She will still be breathing, sugared up! But alive. So you need to take a deep breath and just put it from your mind. And focus on having that baby.
I feel the same way my oldest to I know will be fine there 10 an 5 bur my lil one is only 21 months an I'm super nervous about him not being with me. He's never stayed over night with anyone before so I'm not sure how he will react. An I too am making a list if stuff he likes to eat an his schedule. I know he may not stay on his schedule because it will be a new place but I'm hopeful that she will at least try to keep him on it. At this point I'm just hoping he will eat for her. An I'm hoping I'll only be in the hospital for 1 night an 1 day. So I will be able to get him home asap. I think it's normal to over think it. But I'm sure ur daughter will be fine just like my son.
