As an older Adult Baby, I do carry very small plush friends with me that I can fit discretely into a pocket.
The above is my little "Ernie" Sesame Street friend.
I'd like to be able to do this, but seeing my mother takes me everywhere I go, I'm pretty sure the big lump in my pocket from my Secret Life of Pets Beanie Baby would be kinda noticeable.
My wife would sometimes pack one of my smaller plushies when we would stay with our daughter and her family. You just sleep better when you have one of your plushy friends in bed.
Your plushies are all so cute! I don't have one I carry everywhere, but I have a white tiger named Snowy that I carry with me anytime I go somewhere overnight.
