My son was at the age of 9 months, he loved it immediately! Growing up he found other ways to play with, built, open, close, and now pull the crocodile by its hanseatic which fall under its belly. Eyes rolling, mouth opens, the "safe" and the lovely and funny music (it changes other !! toys and especially his two volume opportunities), a complete toy. My son is quite daredevil, toys must be solid, and this one is very resistant !! A really interesting toy !!! A favorite of my little boy, and I approve his choice 100%.
