Some things that I packed:
2 nightgowns- I didn’t use as hospital provided it
Body wash and shampoo
Lipbalm, compact as I hate an oily face.
Medicines such as thyroid/insulin
Stem cell kit
Baby kit- basic dress, towel, wrap,socks, mittens, cap
Sweater/ shawl/ socks- even in summer you will need it
Feel free to add things I missed in the comments section.
