Okay ladies, my son's 1st birthday is coming up! I can't believe it! I'm planning on having the party February 4th which doesn't leave me much time to plan.. but it falls on a Saturday and that is the day of his actual birthday so ya perfect. I need some ideas about decorations, food, what not to worry about getting, etc. I want to get him a cake smash outfit but the ones I'm wanting are already 30-60$ and he'll need an outfit besides that so he's not basically naked the whole party, lol. I want to do a nautical theme, and I'm doing some of the decor myself. I was thinking about buying a personalized chalk board with all of his birthday stats, it would be a great keep sake too, but they are like a minimum of 40$. I can't help but want to go all out! I will probably be having it inside because it will still be cold outside. Any tips, and suggestions are welcome! TIA 😄😄
