H.,
I completely agree with Jessa on both accounts. My son also went through the clingy stage around 8-9 months. That is when we started using a cloth carrier and it has been wonderful. I can put him on my back, front or side and he loves it. I went to babywearing.com. You can even nurse using a carrier. The website can tell you the pros and cons of each type of carrier and which position works best for each activity and or baby age range. It will also show you how to make a carrier without any sewing that adjusts to you or your husband. That is the one I use and I LOVE it. It is also very comforting for my son to be in while we are out and about. As for making a clingy baby, that has not been the case at all with my son. He is very independent now and only comes to get a hug every once in awhile and then is off for adventure.
The high chair and toy idea worked very well for us too. It is awfully hard to see what is going on when you are less than 2 feet tall : )
As for the let them "cry it out", it worked for some of my friends, but it has never worked for me. It ended up being more stressful for all of us.
Good Luck
