We are expected to be at the NICU for approx 30 days, baby needs surgery within 48 hours after birth...I haven't seen any packing lists for NICU stays and have no idea what to expect as far as how long it will be before Mama can go home and switch out stuff from hospital stay. Is there anything different I may need for the NICU and how many days should I realistically pack for? My bag has necessities that you see in most pack lists as well as 6 pairs of depends, a plush blanket, pillow from home...any recommendations from experienced mamas is needed!! Thanks yall!
