I have an 8 year old and a 5 year old. My neices and nephew (4,2 & 16 months) are also around quite often. Sophie does awesome with all of them. I totally trust my 8 year old because he treats her like a baby. My 5 year old son doesn't quite get it yet. He can't tell between gentle touching and squeezing. So, needless to say he doesn't get to spend time with her alone. Sophie nips at him when he gets too close. The littlest one (neice) can't keep up with Sophie but my sister has taught her about "soft touches" and she seems to understand (better than my 5 year old
). I would be very careful though because even a fall that lands on the puppy could be fatal. Best wishes!
