Also, your party is to celebrate the child turning 1, and your son won't remember or care. The party is more about people getting together and celebrating. They will likely bring presents and warm wishes and you'll have pictures and memories.
Plan a different party, perhaps a picnic at a park where you don't have to pay to get in. Your son will not remember this party so you can really just have the grandparents over for coffee and cake and take some picture for a nice memory..
Try having a small birthday at a park or in your back yard. Plan a few games and if u still want to carve pumpkins or whatever buy a few cheap smaller sones at the store and some cheap carving tools. He won't remember it but it should still be a little fun.
My son is turning one in October, and I was thinking of a pumpkin patch birthday party, the only thing is that they don't have any type of package, it's $75.00 for a party tent (no problem), but then admission is separate. Is it rude to have attending guests to pay the admission to get in? If not, it's a pretty large bill for a birthday, and I still have to purchase food and everything else. If it's not rude, what do I say on the invitation so the person knows? Or should I just plan a different party? Thanks!
