Yeah, he is 9 days to 6 months old. He is starting to sit up. He is 95% in his weight and height group. He was 25% when he was born. He is a chunker. I put him in our kelty kid carrier when he was about 4 months. He didn't like it, probably because he couldn't hold his head very long. I have carried him in the front loader we have a bunch of times, but never for a hike. But, you can't walk fast with those because it bopps their head around too much, unless they are facing you. He hates that. He has to look around. His older brother turns 4 this month and is pretty strong to hike a ways without having someone carry him. We probably should go on a day hike soon. All my other kids have been begging me to go. I am taking my oldest son backpacking on the 10 and 11th with the scouts. Hopefully I will finish his pack in time.
