to the poster who put up the original question i want to talk about the things beyond the crawl track -
as excellent an idea as the crawl track is, it is only the first part of the program. the book takes you from birth to six years old. so even if your baby is too old for the crawl track there is still so much you can do. i started the program with my daughter when she was six months old. now at almost two she has physically reached the level of a three year old -- this is the result of following his recommended programs, walking every day (basically throwing away the stroller as soon as possible
) especially on different terrain, jumping, and our favorite - brachiating - basically monkey bars - but way before she was even old enough to go to the park we would let her hang from our thumbs - this was around seven months and even then she could hold herself up for ten seconds - now she is past a half a minute - finally beyond all this i would really recommend reading the book because besides the practice of it, the charts there really pull all his programs together and gives you useful benchmarks for charting the total evelopment of your child
