J.S.
I have a daughter who is about to turn 3 and this past year has been up and down. She had terrible tantrums right around turning 2 years old and I'd do my best to ignore them, and they went away after about a month.
Then when she "turned" 2.5 they came back, really bad, for about 3 months. I was beside myself. We'd try to ignore her, or put her in her room, but she'd just carry on for an hour. I found the best thing that worked for her was to just hold her until she calmed down.
Yes, my husband repeatedly said he didn't want to eat dinner as a family anymore and there were many unfun nights. I was always on edge waiting for a blow-up/melt-down, so no, you're not the only one. Best I can suggest is just wait it out as it is a phase, and in a few months things will be better.
In the meantime, chocolate. Or martini's. ;-)
