I'm really not sure what to do. DD2 is 19 months. She has been going through a clingy phase for a while now, but recently she has started tugging on my trouser leg and crying/screaming until I pick her up for a cuddle. Quite often when I do she then laughs as if to say 'ha ha gotcha again'. We have been working so hard on improving her interaction and social skills and this is the first time I actually know what she wants, she's quite clearly telling me.
Do I reward her for interacting with me, or ignore this as what I would class as manipulative behaviour (as I would have done with DD1)?
I find I let DD2 get away with so much more than I ever did with DD1 (NT) as my first instinct is if she's upset it's because of sensory overload.
I also don't think it's fair on DD1 as I think it must be obvious that I treat them differently. DD2 gets away with more than DD1 but I can't seem to help it, even though I'm aware of it. (DD1 hasn't said anything by the way, this is what I think).
Does anyone else struggle with discipline and the differences between NT and SN siblings?
