No dancing or chattering here pass! We just get squeals and laughs really!
He used to make a variety of noises, but now not so much, no bababa or dadada or anything closely resembling a word.
I'm not sure why, I haven't changed what we did. We talk to him loads, give him time to answer etc. He just looks at me funny! 
He does do a beavis huhuhuhuhuh laugh, but only when he sees his bottle being shaken!!! At baby group yesterday the leader held him while I ran off to warm the bottle. Everyone was sat in a circle, and as I sat down shaking the bottle O was doing the laugh, much to the amusement of all the other mums. 
In fact he was at his best in the group yesterday, showing off all his skillz. Climbing, rolling, spinning, hanging upside down as I grapple him to change his nappy. He has no fear! Except sellotape and roaring!
Chasing I remember those feelings well. It will get better. I promise. I wish I was so much closer! Stupid distance. Pfffft.
Clarella Oh gosh, you are really going through it. I understand how frustrating it is, trying to find a reason. It's taken a long time for us to find the right combination of things for O too. Trial and error. Fucking sucks :(
