Hospital bags

Ka

FTM here! I see so many “hospital bag” checklists, but wanted to see what experienced mamas have absolutely NEEDED or wished they would have brought to the hospital for themselves and baby.

Also, when should these bags be packed? I already have some diapers and wipes packed in the diaper bag, (newborn + size 1 diapers) but still don’t know what else I’ll need. Breast pump? Formula?

Thanks in advance!!
