Hi Tommy77,
My sentence ’ or did you mean 6-12 months’ was not sarcastic, I really believe that Megan make mistake in writing, because timing 6 m (for sitting) and 12m (for standing) and I hope so because I didn’t like image in my head of child that old put in that positions. In this case I didn’t meant for any particular research, just that in years before was thought that if child don’t seat by 6 m it is not normal and demands treatment (which bring parents to put their babies to forced sitting or standing positions, which, again I believe this is the case), and in now days that line for normal motor development is moved upwards (8m for sitting and 12 m to even 18 m for standing), depending individually from child to child. I think you don need references for this it’s in most pediatric books dated from 2000 onwards.
And if Megan did not make mistake in writing, then I still think it’s very unusual question. Yes of course that everybody have right to ask everything that is what I try to do- to answer, in my own way, we all are different. But don’t look for last thoughts in my writings because there are no any. Like you said English is not my maternal language, like I believe and for majority of people on the site, so don’t immediately jump on the conclusion that someone is ‘ insulting, superioristic or egocentric‘, maybe our English simply are not that perfect as yours…
All the best Natasa
