We're working out when to move DD from cot to bed - i imagine this will involve some getting out of bed hence more toddlerproofing / stairgates - but what happens when staying over at friends / family? can't expect stairgates to be installed but how do you stop her getting out of bed at night and falling down stairs etc?! only thing i can think of is to lock door but that seems v mean and risky in case of fire etc!!
