By 15 weeks old, our little man had developed some catch phrases. He has 3 main sounds that he says all the time like they are his words. There is the ‘hoo’ accompanied with a sigh and then ‘agoo’ and ‘nger’ that he says over and over like he is talking. It is adorable and we love all the sounds he makes. He also makes the cutest little horsey noise that sounds like a horse sighing.
