Ugh, hormones!

I'm trying REALLY hard to not be a crazy b**** during pregnancy, but people are making it so hard. The second my mom found out that we had started putting our registry together, she went online to stalk it and critique me on every little thing I added. My husband and I are pretty intelligent, and we put lots of thought and research into our decisions (especially involving Baby). I registered for a convertible car seat / stroller combo and registered separately for a base. She calls to say, "You know, that car seat comes with a base. You don't need another." I had to explain that we each have a vehicle and it's way easier to just keep the base installed in each car. Her response? "Oh." Yeah, hadn't thought of that simple detail, had you? Then she calls to tell me she read a bad review on something else I registered for. Well, yeah, there's a bad review and about a thousand good reviews. You can't decide against something because one person doesn't like it, or you'll never buy anything! She's nagging about everything and making me nuts. I know she's trying to help and she means well, but crap!!! Sorry for the rant, I'm just trying not to let hormones get the best of me, haha.
