Sorry, I forgot to clarify, she was 6 wks old, she is now 14 wks and still seems to love standing, sitting etc. I work in a general private practice and dont have much paediatrics experience, but I imagine in a normal child, they will achieve these milestones at their own pace regardless of any "training" they receive. We are not trying to teach her anything, we are just doing it with her because of the smile it puts on her face.
Thanks for your ideas.
