So we took our daughter camping with us when she was 9 months old. Early May turkey camp, and it was her first trip.
We brought the pack and play along, but that was only for outside. What we did was buy a down onesie(they make them) and that’s what she slept in over her pajamas, snuggled in between my wife and I. We all slept well. We also had her in numerous bear camps during that bear season with zero issues.
The following year she went along with us to turkey camp in April and spring bear in May. I had purchased a wall tent and wood stove by this time so no issues there. We let her sleep on a small inflatable and she had her own sleeping bag at this time as well. Same with bear camps this year.
The following year we backpacked into a lake and spent the night. While mom and dad had to carry everything, she made it all the way in by herself(it was only 2 miles to be fair, obviously we went at toddler pace) and we had a great time catching and eating fish on the lake.
My wife is due any day now for our second one, and once she’s on the mend we already have camping plans laid out for our maternity/paternity leave that will involve our newborn. No sweat.
My point to all of this is start them young. Seriously. While I would not backpack in winter conditions with a newborn, anything else is fair game. As long as you’re not doing anything too crazy it’ll be fine... especially if mom is along... and once it becomes a normal thing for them you won’t have any issues trying to get them to do it later. My daughter begs me to go camping/hiking/hunting/fishing at least once a week if not more often.
This is the kid that last year, at 4 years old, at 8pm was ADAMANT about climbing down 600 feet to see the bear I shot. The same kid cried all the way back up the hill at midnight... and that same kid completely forgot about the slog up the hill once we got back to the truck... “daddy you shot a bear! Are we gonna go back to camp and eat him now?”
