The cooler bag is for the colostrum to bring it in because it'll be frozen.
There's a ridiculous amount of stuff. I do laugh at people's labour bags because I know from experience half of it won't be touched. Enough for the first day and then anything can be brought to you the next day.
There's nothing worse then unpacking a load of shite after coming home from the hospital. I was a section and no way did I have a shower. I brushed my teeth once in three days
It's funny watching someone pack in hindsight after doing it yourself my first I didn't pack enough stuff and it was during covid so no one could visit or bring me anything and I was stuck there for two days. Second time I packed everything but the kitchen sink and the baby came so fast I was in and out in six hours. Bag wasn't touched. No matter what you pack it won't turn out like you plan!
