You don't need bottles or diapers. Put at least three outfits some socks your own pacifiers they provide some kinds but it may not be what your using. Bring a cute blanket for the day home :)
I don't know about your hospital but mine doesn't use whips there all about these disposeable things u run under water.so maybe whips? They provide whips and if you need bottles for formula or if u use there pump they have them.
Take the extra stuff from your chart when you leave too.
I am a ftm so im not sure how much of a help I am going to be lol but from what I was told the hospital (all are obviously different) gives you diapers,wipes,bottles,pacifiers,formula,blanket..etc. all that stuff for baby and for you they give you breast pads,undies,pads,etc. make sure whatever they give you take it!!!! bc some hospitals give it to you and you might think oh hey why not free but some charge you for it so keep that in mind also for the little one im bringing one cute first time outfit extra onsies and clothes since babys are messy and that's all I have so far lol hope I helped a little bit congrats and goodluck:)
I'd keep some diapers and wipes in the car for your ride home. You never know, he may have a total blowout on the way home. Lol might have to change lol.
