I hate it. We never had it growing up because my mum hates it too. My daughter is only 13m and she already gets excited when she sees it in shops and wants to touch it, so I have a feeling I might need to compromise and do two trees - a tacky tinsel one and my nice one in the living room!
I have also acquired lots if decorations for my daughter already (baby's first Christmas, ones with her name, fluffy things, etc) and they don't really "go" with my main tree so I think we are going to need to do her a small tree for those ones.
