I also wonder how long child <A> has been with you?

I have a 8mos old who isn't with me FT yet, just 2 days a week and according to the parents she doesn't crawl but scoots around the entire house and cruises onto everything, constantly standing, pulling herself up ect. Well I've never seen this child do more than sit there like a bump on a log....not even to reach for toys! It's sit, cry, scream, sleep, eat, sit, cry.....you get my drift.
I even put her standing against those activity tables, showed her that red plays music, blue pops up....and she was good for about 5min then screamed her head off because she was "stuck" in the position. I mean, come on....cruise along or plop down on your bum...SOMETHING! nope

I'm giving it the benifit of the doubt and associating it to her still geting used to me & the new environment. Well see once she's here FT. Because when dad arrived at PU it was the FIRST time I'd seen her bouce up and squeel in joy once she saw him! so I know she CAN do it....she's just choosing not to do it.
