Interesting conversation with a woman in the park today re 7mo ds and what's average in terms of communication.
She seemed rather surprised at ds's methods of communication. He says a few words and has recognisable ways of saying other things that he can't make the sounds for yet. So he says...
Dada
Mama
DD's name
Grandad
Hiya
Uh oh (when he drops something)
Yehyehyeh (whilst nodding and he generally means yes please, hand it over NOW)
Nernernerner (whilst shaking his head and means no take it away wench)
Says 'bahmuh' when he wants milk whilst gesticulating/grabbing at my chest
Says bahbahbah when waving (we tell him to 'wave byebye' so assume he's attempting the sound)
I think it's just progression from different cries signifying different needs and as he's developing more consonant sounds (ba na duh da muh ma guh etc etc), he's just using them instead of crying.
Lady in the park however thinks he's weird and followed us around telling us so and asking me to 'get him to do it again'.
DD was exactly the same. She was 7 months at Christmas and we have some video of her gumming a carrot and shouting 'up' 'guk [look]' 'hiya' 'mama' 'dada' etc. It's the dullest video ever I grant you.
You can have the final say. Is ds a weirdo? I want to know so that I can write it in his baby book along with the more dull stuff about first solids. First suggestion he's weird.
