Language - and Bo Den
"How do they talk? Show me - you do it." LOL, this is not easy. Have you ever tried demonstrating a language you don't speak? I try to remember snatches of the sound of them, to give her some kind of flavour, but ideally we need a website that will play an excerpt of each one. (Suggestions welcome!)
Meanwhile, the baby is learning about colours. She knows they're all different and points to each one in turn, saying her own version of its name. The only thing is (language again) that she seems to think they're all called "Bo Den". Sounds are "Bo Day", possibly springing from bird song, described to her by an older sister as "Birdy", but colours are all "Bo Den".
There might have been a logical process involved in this, I realise, but while she has no more language to explain I can only take it at face value and accept that as far as she's concerned, Bo Den and Bo Day are perfectly adequate descriptions of all colours and all sounds respectively. And by this time next week, they might well be called something completely different anyway.
