You should bring whatever you like that will make you feel most comfortable!! I wouldn’t suggest a comforter. Maybe just a blanket you like a lot. And not too many stuffed animals cuz it’s hard to clean them. Maybe just one or two. I wouldn’t bring something quite as special as a build a bear because it could get messed up! I think hot wheels, legos, a couple stuffed animals, and your tablet would all be perfect for keeping you distracted and also entertained. You’ll probably be a little bored while you’re healing after your surgery. But that’s okay because you will have plenty of time to rest and sleep! Which is always fun!! I especially like the idea of wearing your own pajamas when you go! They will most likely ask you to change out of them right before you go into surgery so that they don’t get messed up so don’t get worried about that. But definitely make sure you have your tablet and charger if you bring the tablet. Don’t forget a toothbrush:) I think you’re going to do great! Good luck in your surgery and I will be praying for you!!!You’re gonna be so proud of yourself for being brave and super strong when you get through all this!! and I will be too!!! Good luck!!
