Ds is 11 months, he has just started standing up on things and has been crawling since about 9 months but is getting round pretty quick now. I have noticed since he's started getting round more that if I shout his name or 'no' he has absolutely no response.
I could be sat next to him repeatedly calling his name but.. nothing.
He's all smiles and has good eye contact. He says mummy, Dada, hiya (whilst waving) to people, plays peek a boo with a blanket, claps hands when asked and wags his finger when I ask him to do tick tock (like a clock)
Other than this he has no words, I couldn't say get me the ball and expect him to do so, doesn't know what his feet or anything are yet. Should I be concerned?
