The Museum of Childhood in Edinburgh is a super cool place that's all about toys and playthings from way back when. It was actually the first museum in the world to focus on the history of childhood, which is pretty awesome. The collection has over 60,000 objects, ranging from the 18th to the 21st century. It's got everything from teddy bears to dollhouses with working plumbing systems. The museum recently had a major makeover, with new display cabinets and lighting, and even a digital photo gallery showing how kids grew up throughout the 20th century. Best part? Admission is totally free! So if you're ever in Edinburgh, make sure to check it out and relive some childhood memories.
