NATURAL HISTORY MUSEUM>>Invalidenstraße 43, 10115 Berlin The Natural History Museum (Museum für Naturkunde) is a great place to explore for a few hours with a toddler. The famous dinosaurs are in the first hall you come to but the rest of the museum is worth exploring. The museum runs regular special exhibitions so it is worth checking their website to see what is on. Important to note the museum is closed on a Monday. There is an entrance at the right hand side for strollers.
