feeling overprotective

I know as first time parents we will have a lot of learning to do Between me and my husband. I've been taking time to read and educate myself about things (and freak out over things that haven't happened yet!) for instance we have 2 dogs that my husband walks ( they are too strong and pull me too hard right now) and we got a jogging stroller ( and clip on fan) because I'm sure I'm going to want to walk a lot to get back in shape after delivery. Well my H insists that he wants to carry the baby himself in a front carrier facing out. So I'm just panicking already over th fact that they can't face out until they have head control, and I worry that he won't be able to breathe and it'll be too jarring on his neck and what if he overheats. I don't want to be a crazy mom already and make my H feel bad but i can't help but worry that we are going to make some stupid mistake and harm our precious boy.
