Congrats on getting them out in the woods and enjoying some family time. Consider bringing jiffy pop popcorn on the next one. It's a staple on our daddy-daughter trips and it always gets a smile from other backpackers when it's dangling from her pack. It's also a bit of a game to see who can achieve the perfect pop.
The kids look like the are having a great time... maybe some future thru hikers in the family...enjoy!
