I need help!!

I need help! I am flying to the USA for about 6 weeks in summer (from UK) and I need help deciding what stuffed animal friend to take. My options are my cheetah blaze (medium), my lion Theo (small), my other lion godrick (small) and my wolf/husky phoenix (small). I love them all so much and want to take them all but I doubt I can fit them. I don't know who to favour - do I take the most special or one that I haven't bonded much with? (Assuming that I won't lose any of them!) I think I can probably fit either 1 medium + 2 small or 3 small.

Does anyone have any advice on how to choose? And does anyone have advice on travelling with stuffed animals in carry on? Thank you for reading! 😊

Edit: I am pretty sure I would like to take Blaze as he is good for snuggling, but the other 3 I am still undecided. And will any of them be taken away when going through security?
