Genuine question: how the hell am I supposed to stop a crawling and (as of this week) occasionally Bambi-style toddling when he can be arsed DS from grabbing and pulling a 7ft Christmas tree down on himself?? 
We can't just not have one, 5yo DD would never forgive us. But the thought of spending weeks being worried about taking my eyes off DS for a second because he's constantly trying to chew the Christmas lights or throw all my lovely, very breakable Christmas baubles at the TV is a tad stressful to say the least.
With DD it wasn't an issue- if she touched something she shouldn't we only had to look at her and say "no" firmly once and she'd never go near it again. She's just that sort of kid. DS is a whole other story! We've had to baby-proof the entire fecking house because he's into everything, all the time. But how does one baby-proof or toddler proof a Christmas tree??
Help me oh wise ones!
