My dd2 had a handful of words by 7 mths but sat on her bum refusing to walk until she was 16 mths
All that talking wore her out i think
She sounds very clever. why waste all that energy on walking when people are willing to carry you? I use that to justify the fact that i didn't walk til i was 18 months old!!
I think she just decided sitting there talking was the more sedate option, rather than charging around the furniture. When she did walk she never toddled either. Just got up and walked clear across the room, as steady as you like! It was great - no stair gates needed etc.
Anyhow all that talking, must be very bright i thought
up until about year 2 the teachers would say how her comprehension and understanding were way ahead of most of the class. Then they all gradually caught up. She does use some good vocab in her writing though.
