Cool on you for taking the little one w/ you.. By choice or neccesity, it's a good thing! That being siad, I give you an extra 100+ points for hauling a little one in a trailer on nobbys! WOW!!! Thats some work there! If you ever put yourself on a fast little road ride after hauling that weight, you'll be like a rocket! No joke, those trailers are heavy!!
Being a mom who had her son in the jogging trailer at the ripe old age of 7 weeks, I have to say that this is a time you will remember years down the road. I have pictures of him and I in a local 10k. He wore my race # and had his sippy cup in his hand. I think he was 2-3.. It's one of my favorite race pictures to this day. Enjoy this time w/ your little one, and know that you are teaching him/her a valuable lesson about being outside and active!
Cheers!
