DD crying, won't sleep, how do i know if she is just 'tryjng it on' or not?

[pickledlily]

She's 12m. DH is trying to get her to sleep, she's had Calpol and Nurofen. She has been crying/whinging now for 30mins, DH says she's trying it on and just wants to get me in her room (I'm ill and supposed to be sleeping, fat chance with the noise).

Am I the only person in the world that can't tell the difference btwn a real cry and trying it on? How do you know? To me she just wants a cuddle but DH seems to be on a mission to settle her without me. It's upsetting to hear her upset but maybe I'm being too soft
