CRAWLING IS IMPORTANT! Sorry, I don't tell often

but it really, really is important. We actually strategically placed our furniture to discourage crawling!
Cross pattern movement is extremely important for brain organization. There are many other benefits as well such as eye covergence & even fine motor from having their hands on the floor.
From a neurodevelopmental standpoint it is probably the most important activity you can do.
This is an early learning community so naturally the focus is more on learning but there used to be a community called Child Brain which focused on early learning like math & reading but also on a broader neurodevelopmental approach. The belief there was that while all areas are important if you have only time to work on certain areas you should focus on the physical because that will help with the brain development which will allow the book type learning to happen more easily. Look into Glenn Doman's methods/books if you are interested.
Frukc - what a wonderful attitude your country has!
