I can remember the exact day, it was last February (2011), Bethany would have been 1 yr 10 months and I remember it because it was the evening before we were going to the Lake District for a few days and she had a tantrum the night before and was in a foul mood the whole time we were there. TBH though, she has only had about 5 tantrums and luckily she has never had one outside.
Best of luck x
