dd (2.1) says no to everything even when she means yes.
I know:
it's partly a product of hearing me/daddy/cm saying no to her.
she might find it more difficult to say the word yes.
she's starting to be a little person and this is possibly a way of her asserting herself (or trying to)
but:
I find it a bit depressing.
I am trying to say yes lots more than usual and am encouraging her to say yes but it's not working so far.
Any tips?
