Charlie's lovey is one of Mr. Bee's t-shirts. He is not picky about any particular one (we have them in a bunch of different colors and he uses the old ones). He likes to rub the stitching on the edges. Before he adopted that lovey he did the same thing with his onesies (so he wore them until 24 months when he adopted his new lovey).
Olive's lovey is the aden + anais blanket and she's not picky about pattern.
So luckily we don't have to worry about losing them!
Is your LO picky about a specific lovey?
