my lovely ds, 15mths, is really driving me potty. I know it's developmental, but I thought it would come a bit later. climbing onto everything, dancing on the table and singing, emptying every cupboard, bookshelf etc. The house is pretty childproof, and it's only the dangerous stunts I'm worried about, not damage to our stuff. however, tell him NO repeatedly & firmly and he'll go back again & again. remove him & he'll have a hissy fit. Distraction does work, but I feel rather weary of coming up with new things every 5 mins. And I'm really bored of hearing myself saying NO all the time, I try not to have too many no's usually, only to dangerous things. He's always been active, but now he's really pushing the boundaries. My problem is that he's too young to reason with, unlike a two year old who may be able to reason (?) a little more. He has good language skills and can understand nearly everything and make himself understood with words, grunts and gestures. How long does this stage last? Any top tips for stopping him driving me mad?
