Hiya Cass, no, the baby doesn't seem to respond to the birdie, not that I'm aware of anyway. That's cute about the wolf whistle. Lenny makes cute noises sometimes which I'm not too worried about, but sometimes he can get really squarky when we leave the room and won't stop until we come back. It's these times that I'm worried about.
I assume he likes the company and so previously I've tried to take him with me when I can. I just know that when I have the baby I won't be able to take him with me. Over the last few weeks since posting I've been experimenting with him, leaving for a while, trying to positively reinforce quiet behaviour, but I think it's just going to be something the baby has to get used to. I've just got to remember that vocalising and enjoying community is natural birdie behaviour and its probably just not realistic of me to expect anything different...
