Currently we are planning for DD's first birthday party. We are preparing for a crazy room full of 1-2 year olds and their parents. I'm starting to think of all the things that could possibly be overlooked or turn out to be a REALLY bad idea and go horribly (or humorously) wrong.
So far I have decided not to bother with a table cloth as I have seen what can happen when a toddler decides to go walking with it.
So what was your biggest birthday party mistake?
Please no 'Inviting my family/friends/coworkers because we had a big fight and it was just awful'
More interested in hearing about the things you forgot or didn't plan for which gave you that 'Doh' moment.
