And when were they able to stand while holding onto something? LO was sitting around 6 months, crawling around 7, and just started pulling herself up to a sitting position right after 8 months. She seems to be wanting to stand, but she can only stay up for a few seconds on her own. I'm not really worried yet, I'm just curious since I seem to read about a lot of other babies her age or younger starting to pull to stand.
