Hmm not sure if these have been said
1. Eat things throughout the day when getting ready, even when you aren't hungry. We had mini yohgurts, museli bars and fruit platters available all morning while we getting ready to just graze and snack on so I ate without feeling like I was eating IYKWM!
2. Pack snacks and water for location shoot. I had a little cold bag with those mini cheese and cracker snack packs in there, and small bottles of water. By 4pm we all realised that we hadn't eaten or had water for HOURS so we had a mini picnic on location!
3. Eat your dinner. or lunch. Or canapes.Or whatever it is that you have planned and stressed over. It is too easy to get caught up and not eat, but food was a big part of our reception and I made sure that I stopped and ate with my husband on the night. And even sat down and ate my cake (and some of his) without him
4. Ok one not about food. It was organising the little details that I enjoyed the most - in the planning and on the day. Most people aren't going to notice everything and it may not be traditional, or have done before in your family or whatever the reasons are. But looking back, it's the little, quirky, 'personality' parts of our ceremony/reception/decorations that stand out and made the day ours. It doesn't matter what anyone else thinks, do it if you love it.
5. Something will be less than perfect. It is called odds. You are dealing with so many vendors and objects and details and variables that inevidably something won't work our perfectly. Accept it now, and don't give it a second thought on the day. My DH and our groomsmen forgot to put on their lovely orchid buttonholes and left his parents corsage/buttonhole behind as well. Shrug. Our band wasn't as seasoned and professional as we'd been led to believe. Shrug. One of my cousins who I didn't want to invite but had to was a psycho and did her best to steal attention and be a general git. Shrug.
You get the idea.
6. And lastly. Families are strange entities and for some reason the reactions and behaviours from some family will be unexpected when it comes to weddings. Sometimes in a good way, more often, not so much. Try not to get sucked in to the vortex of emotion and try to believe that everyone loves you and is just trying to help. And then only do what you really believe is the right thing. It is true that a marriage is for the couple, the wedding for their community but only within reason so make sure it is a day that reflects what you think is important as well as having a happy Mum and Dad.
