Hi there! I was going to read your responses first before I wrote, but there are so many! So, I'll just tell you about me and my experience! My son is now 19 months, and was born just a couple weeks before Christmas (December 3rd, to be exact). Around the time that his first birthday was coming, I was having a really hard time in life... one thing after another.... 2 car accidents, starting a new job, getting the flu, a sick kid, my car broke down... I just couldn't pull things together enough to plan a party, get the invites out, etc... so, we ended up having a small little party at his daycare, then we went out to dinner with family. Well, I was feeling horrible that for his very first birthday, he never had a big awesome party! So, I decided to do one in June... just had it a month ago. When I invited people, I explained the circumstances... that it was a belated birthday-funn BBQ-friendly get together... all mixed into one... I even told people not to worry about gifts, but some people actually brought some anyways! After the party was over, I was SOOOO happy that I made the decision! It was so fun! We had decorations, and balloons, all outside, a BBQ, lots of friends... it was just so much fun... I did have someone say an off-comment about the fact that it wasn't his birthday, but I just ignored it. Everyone else however had a lot of fun, and was also glad that I did it.... we had about 30 or 40 people total. So, long story short, I think it's a great idea. And, I've decided to do it every summer!
