I made these Discovery Bottles for Master M when he was little (#notsolitte), to enjoy when he got a bit older. Now at 10 months old, I can tell you, he plays with them every day - and loves them, especially the button & beads bottle (because it makes a LOT of noise). They are easy to make: all you need is an empty bottle & a collection of items of your choice to pop inside for your child to enjoy. (For safety purposes: please ensure that the lid is sealed tight, hot glued or taped closed).
