TalktoMeNow, I saw you mention that Jasper likes to drink water... did that coincide with his weight gain slowing down? Does he nurse less now that he drinks water? Just a thought.
Also, where is he on the WHO (not CDC) height and weight charts?
ZippyGirl, we've also been "breaking the rules" about introducing one food every four days - but so far, we have only given A a few types of organic fruits and vegetables. No berries, citrus, dairy, grains, etc. Her favorite so far seems to be pear and pea puree.
I also got A's high chair secondhand, off of Craigslist. The high chair and two bags full of 9mo clothes (in nearly new condition) were $60 all together! That probably doesn't seem like a great bargain to some people here, but we live in a HCOL area...
