yep my Syd seems to be the same as Isaac above,,6 months old now was quite quiet when he came home for a while,,now whistles a ton, makes birdy noises and the last few weeks we can now tell he is trying to say hello,,,and some other things we cannot make out,,but definitely is trying to say more things as he has a deeper voice when he trys to talk.. also has started a beeping noise which sounds like the microwave etc.
