My hospital didn't have conditioner at all. An the shampoo put my hair into a huge ball of knots! So I recommend that conditioner is a must! (If you use it)
I barely used anything I packed because the hospital really provides so much for you and also I was in too much pain, so to be necessary I would say...
For you & baby - going home outfit
For you -tooth brush tooth paste , shower shoes & slippers
Breast pads if breast feeding and sports or maternity bra
Hair supplies maybe robe
For baby - socks ,mittens and nail clippers .
Hospitals usually provides , wipes ,diapers,pads,underwear,towels,wash cloths , soap, lotion, body wash & shampoo , comb for baby , lotion for baby , & bodywash for baby , shirts for the baby also blankets and hats for baby .well at least mines provided the above !
