I'm 34weeks and have yet to pack my bag.
I'll probably wait another 2weeks before packing the bag and washing the babys things.
Most hospitals provide you with bottles, formula, diapers, pacifiers etc while you're there and some to take home.
The only thing you really need are 1 or 2 onsies if you want him changed while there and going home plus the carseat.
The hospital bag is pretty much things for you: shampoo/cond, pj's, slippers, camera, phone charger, underwear etc and some things for hubby...
I would pack asap and take diapers clothes formula bottles pacifiers sock blankets and a water for u directions for who ever will take u a watch for the dad
