text: First of all Congrats! I am celebrating my sons next month! I'd pick a theme...which you said you have...check either some party shops or online stores like birthdayinabox.com and see what is out there to go with your theme...then buy some things to decorate, order a cake and use plain cheaper plates, napkins ect that color coordinate with your theme. Mail out some invitations...of course it will mostly be family probably...and even send them to people who are out of state...even if they cannot come they will most likely send gifts, esp for a 1st Birthday. Then the day of the party, set up, lay out some snacks (oh-plan the time for when your child is in a good mood and not around a meal that way you can just provide finger foods rather than a meal). Make a timeline for the party to keep it flowing...and SMILE! It'll be a blast no matter what...oh-another thing I'm doing...if you either don't mind the mess, or plan it for outdoors...make you child a special cake for them to devour and play in :-) Have fun!
