Freak out moment

Hello mamas.  So I'm 14 weeks and I'm working on a Baby's R Us registry just for fun right now.  Idk the sex of the baby yet so I can't get too crazy with it and everything I'm adding isn't final. But I looked at the check list and the different products and I realized that I have no idea what I'm doing.  Like, I didn't realize there were so many different types of strollers or high chairs, etc.  What kind do I need?  Do I need more than one???  And the more I think about it the more I freak out.  Anyone else feel like this?  I know that I can ask questions and a lot of it will come naturally but right now I'm kind of scared.
