Nearly everything is completely unnecessary. Especially qubies & pureed baby food in a tube. Some things did make life a bit easier though - MCN's, ergo carrier, bumbo, high chair, a very small % of the toys my kids have and a fraction of the clothing they had for example.
I don't have a problem with it, in general. Businesses need to promote their products somehow or they wouldn't sell anything. Newsletters & magazines etc - no-one's forcing anyone to get/read them so that's fine. I love getting them, but I don't always read them. Same with things like FB - no-one forces anyone to like a page or keep reading their updates. I have had heaps of sites on my FB but I haven't kept ones that I found I didn't need or like. I would have an issue if a "mummy blogger" was promoting a product for cash and not disclosing it though. It's deceitful.
