D.P.
I would stock up on diapers! A stroller and a good car seat. Also, if you're not breastfeeding, bottles.
Maybe a bottle draining rack for next t the sink and/or a dishwasher basket for the rings & nipples.
Crib, blankets, maybe a bassinet and/or pack & play of you have a 2 story house and some napping will be done on the first floor. (This will save you some running up & down.
A baby monitor is nice to have. I loved my video monitor. Really, when they're brand new, they don't need all the bells and whistles....OH! O. thing I really liked was a vibrating bouncy chair. Congrats & God Bless!
