Books on that tricky second child?

[Errrrrrr]

DD is 2 years old and adorable but right in the terrible twos. DS was a pretty easy toddler and I'm worried we are letting DD down by not dealing with this right. She bites, tantrums, is generally defiant and won't listen. I wondered if anyone could recommend any good books which might help us work with her better, particularly in the context of her being a second child (which I think is relevant to her behaviour - trying to make herself heard etc although we try to have time for both). Would welcome any suggestions!

I’d try 123 Magic. How’s her speech too OP? They can often be very frustrated at this age if they don’t feel able to communicate properly. My DC1 used it to their advantage and used to subtly wind DC2 up because they could run rings around them verbally.

It's not about being a second child but I really like 'how to talk so little kids will listen'

Another vote for how to talk. The little kids version is supposed to be from 2.

Thanks for the recommendations, I'll take a look. Speech is fairly good and she's pretty adept at getting her point across but obviously she's not as good as her brother which must be frustrating for her. Thanks again!
