Preparing for baby

I'm a first time mom and I'm 16 weeks. I'm so overwhelmed with trying to prepare for my new bundle of joy. Mine and my husband's family haven't been any help when giving advice and it's starting to really frustrate me. My mother says "it will come to me," while my MIL says we are "rushing it" and starting "too soon." When I ask for what I should put on a registry, I just get the same answer "bottles, swaddles, and onesies." Is there anyone out there that can possibly help me so I won't feel so overwhelmed?
