Pip does not care for them, they are Not to Be Trusted. To be fair, he feels that way about a lot of strangers. But he's actually been exceptionally tolerant of them on the few occasions when some artful dodger has gotten around my body blocking. Once I almost had a heart attack when a little kid came out of nowhere at the park and hugged him before I could even react (and before I learned to be extremely witchy and yell at kids) but he just stood there looking miserable. And a couple of times with respectful wee ones at family gatherings he just keeps his distance and does his thing, but doesn't really react to them otherwise.
Squash likes to watch them before deciding to engage. And he is sometimes hesitant about kids who are at that crazy pre-teen age depending on how they approach him (but hey, so am I). But generally the wee ones he ADORES.
Maisy loves everyone, always, forever.
