Ok party mamas, I'm trying to figure out some sort of activity/entertainment for my daughter's first birthday. I'm not looking for a service/entertainers, just ideas geared towards 1-5 year olds that is inexpensive, fun, and easy. My sons birthday is in July so we always just get a few kiddie pools/water play centers and let them go crazy but, with my girl's early March birthday the chance of cool weather counts that out. I've been interested in getting ball pit balls and filling kiddie pools up with them but when I priced it out I realized it was going to be way too much ($20 for 100 and we'd need at least 1,000 + pools) and we'd end up with a bunch of unwanted balls. Ideas please???
