how long do your 7-8 month olds sit up by themselves?

honestly as long as I leave her or until she decides to crawl away..

does she ever get tired or pist off from sitting up that she falls back @heather-sophia.

not now she use to or she'd purposely throw herself back

when did she stop doing that? kyler does it so I stay near her @heather-sophia.

I don't remember.. you could always put pillows behind her and just let her sit on the bed or something
