Its interesting to see how they develop differently.
Evan was really early for Crawling & walking. He was crawling by 4/5 months & walking well by 9.5 months. Yet he took ages for his speach to develop well.
Glenn on the other hand wasn't walking well till about 13 months. Crawled around 7 months I think. It was weird (and hard) having him take longer to do those things as Evan had set the "normal" for us at such a young age.
It will be interesting to see how Isla develops these skills.

Kerrie, Like you said, as long as Jay is meeting something new each week etc, don't worry.
