I have read a few blogs from people who followed the Nancy Thomas method for attachment, but had not ordered the CDs "Taming the Tiger While its Still A Kitten." I left a post on RQ asking people about using an Ergo for a 3 year old and got mixed responses. The post kind of turned into more of a "theory on attachment" kind of post, which wasn't really what I was looking for. I just wanted to know if an Ergo would work for a 28 lb child. I listened to what everyone had to say, and vacillated myself on whether or not to "pouch" Cara and use Nancy Thomas' methods for attachment. I bought the CDs and listened to them twice. I really think, for me, that the Ergo is going to help with attachment, so this weekend I bought one at REI. I went with the Ergo sport since it has more venting to keep Cara cooler. We'll see how it works, but I think our family is going to try to follow this method. I work in a school as a VP and my "frequent flyers" for discipline issues tend to be kids who have issues with attachment, so I know how important it is. I will keep you posted on how it works!
