My daughter is 8 1/2 months and she isn't sitting up yet, my older daughter also wasn't laughing at that age either. How is your daughter developing in other areas? If you look in the 'your baby' section you will see a topic that I started a few days ago worrying that my lo wasn't sitting yet. The replies I had seemed to show that it wasn't too unusual.
