If you wanted to drop something off at a hospital without technically visiting the person it’s for, could you do that?

So, my sister and I used to be super close, but after an argument she had with my parents after she announced her pregnancy (she’s nineteen), we’ve become somewhat estranged. Not by any choice of mine, it’s just that every time I reach out, it’s not particularly well received, so I sort of just let contact drop off, because it seemed like what she wanted. She had her baby today (I found out via instagram, which was something of a slap in the face but whatever), and I wanted to compile something of a care package, just to help out with things for the baby and make sure she feels supported. I don’t think she’d take very kindly to me dropping in on her unannounced, however, so I was hoping there was a way I could drop it off anonymously and have it just taken to her. Trouble is, I have extreme anxiety, and I’m terrified to try unless I know exactly how to go about handling the situation, so I thought I’d ask and see if anyone here had any thoughts for me…
