I’m really into buckles nowadays. I find them fascinating. And they are everywhere on baby related things: booster chairs, car seats, strollers, baby carriers, bags, etc.. I think the way they lock is so interesting. I’m still working on trying to buckle things up on my own, but it is a bit hard for me to do right now. I’m sure I’ll figure it out soon. Until then, I just love touching the buckles, chewing on the buckles, and examining the function of buckles.
