That's great. Keep doing this as much as you can. Not everyone has the luxury of being able to spend much time with their kids, so if you do, don't squander the opportunity.
It's going to be harder to keep these boundaries as your daughters grow older and their natural personalities develop. They'll likely take interest in whatever their friends and social peers are doing, and the two of them may go off in wildly different directions. Stay engaged and be ready to adjust your parenting techniques as the girls grow older.
