Growth Guides - Physical development: Crawling, Walking, Climbing

I got a book from somewhere. It was published by ParentsCanada. One section in the book is growth guides. It categorize children development into several parts - physical, emotional/behavior,intellectual, sensory. For each part, it lists very detail development items for parent to record the first time that item is observed. It can be a great growth memory recording. ChenChen will be 2 years old in about a month. I figure I'd better do this recording now before my memory is completely gone. I only know the thing about after 13 months. Even then, the number I put there is still maybe/about number.

- Point with first finger  - 13 months? should be earlier than that

 - Crawl up the stairs - 16 months

- Walk alone, try to run - around 15 months

- Push and pull a toy while standing - around 15 months
