My 11 week old seems a lot older than the other babies around her age that I have met, I know they all develop at different rates but she seems REALLY different to the others so I wanted to check that its fairly normal before I go shouting my mouth off and boasting only to make myself look stupid 
people have always said shes very alert, even from birth
from birth shes held her head up with no problems and looked around
she made and maintained eye contact for long periods of time from about 6 days
she has sat up with little support from 5 weeks
this is what really gets me- she stands up with VERY little support and has done it for longer and longer in the last 2 weeks or so
is this normal? I am a very naive first timer and have very little experience of babies, I weent to the childrens center for the first time last week and all the other babies (many are older than dd) just seem so tiny and weak and 'baby baby' IYKWIM?
