What did you do for toddler-proofing if your 2 yo (2 yrs, 2 mos) suddenly developed climbing superpowers? DD(2) climbed out of her cot, i tried to co-sleep with her in the big bed (she hates co-sleeping) and after 2 hours I'd fallen asleep and then I heard a voice saying 'mummy, mummy' and she'd gotten over the stairgate (her bedroom door was open because we have a stairgate on the top of the stairs) and she had walked to the bottom of 2 large flights of stairs without incident. I'm shaking - I can put covers on the door so she can't turn her bedroom door but it's a nightmare that she can get over the stairgate if anyone forgets to shut her door properly. Any ideas?
