I tent camped at the Fort with a nine month old baby. I learned some hard lessons during that trip. Wherever you are, be prepared for the weather.
They make relatively cheap window unit combination air conditioners/heaters now. I would invest in one. There is nothing like a cranky baby who can't take a nap in the afternoon or get to sleep at night because it's too hot or too cold. Even in a tent, you can use some duct tape, plastic sheeting, and a flexible dryer vent hose to pipe cold or hot air into the zipped down corner of the door of your tent. Your sanity and enjoyment of the trip are well worth the cost.
If the weather is fair and you don't need it, then it was a small price to pay for the peace of mind it provides. Given by your post, you tent camp often so you may very well use it on a countless number of trips in the future since it doubles up for both cold and hot weather use. Believe me, it's worth the storage and hauling space.
Use a Pack-N-Play. I thought I would simply let my daughter sleep with me since I was breast feeding her. Wrong. I lost countless hours of sleep worrying that she might crawl away (even though she couldn't crawl at the time). Set up her own sleeping place. It helps.
Also, you might want to set up a baby care area. This might not be a problem at home or when everyone is up, but changing diapers in the middle of the night can get a bit tricky. Hang a divider between your sleep area and the baby area (one usually comes with a cabin style tent and even some domes) and have a soft light available. Stumbling around in the dark half asleep is not good. Plus, it keeps everyone else from waking. With a baby care area, you turn on the light and can readily reach for everything you need all at once. No searching for diapers or wipes in a diaper bag where you packed everything that happens to be sitting out on a picnic table because you were so tired when you got back that you dropped everything and collapsed after spending hours getting the baby to sleep. If you bottle feed, keep a cooler with ready bottles handy. Otherwise, you might want to pre-fix a place where you can lie down and nurse without disturbing everyone else.
I'm still kind of hoping we'll have the reunion somewhere else this year, but I don't think that'll happen! Any other suggestions/ advice would be great.
