HELP!!! -BABY SHOWER PLANNING

Ashley
what were your favorite games? 
What kind of food did you have?
Your theme?? 
And what was the budget/cost of the shower entirely? 
I'm a second time mom and someone threw me a shower with my first. My second baby shower I'm planning with my best friend. I want it to be perfect. There will be around 70 people or so as it will be co-ed (yes I'm the most untraditional person ever)  So to feed everyone it's gonna have to be inexpensive. 
Also were children allowed at your baby shower? I'm thinking about getting a sitter for the day so I won't have to be chasing my son around and tending to guests.
