Hi, I am thinking about getting a structured carrier (like an ergo) for my 2 month old ds. I think dad would feel comfortable carrying him around outdoors with something structured. But which one? and at what age can we start? I have a hotsling now and we bought a babyhawk, but the babyhawk is awfully big on me since I am so short and he really cant hold his head in it too well yet. I am hoping he will grow into it and dh can use it but wanted to try a structured one now. He always comments on people carrying thier baby in a snuggli type carrier, so I think he would prefer a structured one. What are your favorites and why?
