Do you just let them get on with it to a certain extent?
DDs 1 and 2 , I have come to realise, were relatively abnormal toddlers! They generally stayed by my side, weren't that interested in cupboards. Although they were both fascinated by the fireplace.
DD3 has just turned one. She is perfecting her toddler tantrum and is a lot more pesky inquisitive than DDs 1 and 2 were. She would appear to be a bit of a climber (I am hoping and praying she doesn't turn into one of these cot/ stairgate mountaineers). She is currently climbing up and down the ikea childrens' table and chairs. I am near, but I'm letting her get on with it because thus far the DDs appear to have been fairly self-limiting; only doing things they're actually capable of. But they didn't climb up and down furniture at just one.
Somebody just tell me this is ok, I'm having a paranoid moment and DH is working away!
