Yes, a discussion and a half! The enthusiam and passion is great! Yes it's a question of a child developing at it's own rate vs exposure it centain positions. I face this battle everyday in my clinic where mothers are either doing too much or too little to facilitate normal development of the infant. I too do not support jolly jumpers or walkers and there is reasonable evidence to support their non-use. Teaching a 6 month old child to jump when they are not yet sitting is a case of common sence lost in our world today. Both have evidence for the danger in use (children can access things they otherwise couldn't-jug cords, christmas trees, hot coffee-you name it) On the other hand some parents don't do enough to help the little ones develop-especially low tone babies- floor time is essential, rolling, sitting, commando crawling etc. It doesnt take a rocket scientist to work out if a child has enough muscle tone to support the position they are in, early sitting is flexed and I havn't seen evience to support wearing of joints etc at this young age. How is a child supposed to sit if they have never been exposed to the position?
