Sometimes dinnertime is horrible, sometimes it's totally fine. (my dd is 2 1/2 btw) There are some nights when it seems the idea of everyone sitting down and eating is just totally unbearable to her. So we generally just tell her that it's time to eat, and if she doesn't want to sit and eat that's okay, but mommy and daddy are going to eat. We show her the clock and explain that when the hand moves from 3 down to 5 we'll be done (she gets the concept). Then one of us usually tries to hurry up and finish eating so the meltdown doesn't last too long.
I figure it's a bit of a phase, and I know for us that it's more of an issue if she's tired, or needing to poop, or if there's something else going on, like teething.
