S.B.
i camped for the first time with my son at 9 months old and we did a tent. We have a pop up now, but often use the tent instead on cooler trips because it keeps warm better with our body heat.
We used the pack n play too. It was only 40 degrees at the coldest when we camped, but footie pajamas, knit hat and a blanket kept him toasty. Make sure you keep the pack n play away from the sides of the tent because they tent to get condensation and if her bedding is touching it will get damp and uncomfortable.
I also couldn't have lived without the super yard. I brought a big blanket and put the super yard over that and he could explore without me having to keep a constant eye on him .
I also invested in the pre-mixed formula in individual servings because I wasn't sure about the water supply at the camp ground.
the other thing I thought was worth the money was a battery operated fan - it takes a huge amount of batteries but really helped keep him cool during the day and kept the bugs off of him.
i also used the back pack carrier quite a bit and the mosquito netting i found for his pack n play. That made it easier for naps outdoors.
I brought at least two changes of clothes per day because he got so filthy and there was the possiblity of ticks where we were so I wanted to make sure I was keeping those off of him. I also used a baby friendly bug lotion.
I was terrified about the camping because we were gone for a week but it was a great experience.
