I just gave all his old uniforms to the thrift store.I'd ask him what his preferences are. Will he be able to do buckles? If so maybe an ergo or similar soft structured carrier. Is he willing to learn ties? Then perhaps a mei tai (I know a dad who's wife had his mei tai made out of his army clothes, can't remember the name now).
Thanks! I don't think he's planning on going out with the baby by himself at first either...more something to wear around the house since he's home a lot, or maybe when we're out together.I think he was fumbling a bit with the newborn stage and really doesn't go out with the babes alone until they are toddlers and much more prone to walking.
But since your hubby has expressed an interest there are definitely carriers that fit bigger guys and/or WAHM that make carriers and can make one to fit your husband.
