For Mama:
Maternity pads & panty liners
Perineal Spray
Wash bottle with spout
Breast pads
Lanolin nipple cream
Nursing bras
Nursing-friendly tops & loose clothes
Breast pump & milk storage bags
Suitable pillow for nursing (optional)
Swim ring / doughnut to sit on (optional)
Postpartum girdle / wrap
Scheduled postpartum massages
Large water bottle
Vitamins
Nutritious snacks
Entertainment (e.g. Netflix)
Pain medication as prescribed by hospital
Hope this helps. Do let me know if you have any questions :)
