I'm not even going to try to lie to you.. when I first saw that other soon-to-be moms were entering giveaways and winning, I was totally eager to do so myself. I basically found some blogs, followed them, and entered their giveaways. I would NEVER un-follow on GFC or de-friend them on Facebook though after a giveaway was over, common sense says that's rude.
Call it experience with this, or whatever, now I know better. I now find blogs that I legitimately find helpful or otherwise like the content, and if they happen to be hosting a giveaway, great. I have definitely learned that you don't follow blogs strictly because of giveaways.
Now, I also have to admit that I found One Smiley Monkey because someone posted about their Charlie Banana giveaway on their page, and I went to go look. Honestly, I wanted to know who the smiley monkey was... her son! But, I flipped through the rest of her blog. She has done a ton of research in family-friendly and/or natural products to help your family. Her blog has everything, from reviews of nursing reminder/log bracelets to travel cribs. To make it even better, she started the blog in February! This makes me happy because there are probably lots more reviews coming.
So, yes, she has an awesome giveaway up for Charlie Banana from Happy Eco Baby that's valued around $300. Yes, I think you should enter it. And also, I think you would benefit from the extensive research and reviews she already has up on her blog. But please, whatever you do, don't follow just for the giveaway.
