I know its prob just her age, but struggling with DD's behaviour.

No advice but we are going through this with L too. Driving me batty! Every time he does something naughty and gets told off for it he thinks it's "funny". Time out doesn't bother him and nothing is getting through to him. W is going through a clingy, whingy phase so I can't give him as much one on one attention as he wants and I just dont know what to do anymore. Your not alone!

I came to this thread to write almost word for word what you have written. So if it is any consideration you are NOT alone. I keep thinking that there must be some magic phrase that I should be using or some brilliant technique that I have missed in all those books but I think it's just plain attention seeking and jelousy of the younger sibling. (mine is 3 years and one month with a 16 month old sister).(pretty close to you I think (22 months apart) ... Soldier on Mum. Apparently it gets easier!..Im freaking out actually as i have number 3 on the way with almost the same gap...
