We have had a couple of opportunities to have nephews hang out with us, and my kids have loved it. Jake, who is really not a baby anymore, stayed with us for several days while Dillon and Nicole went on a much needed cruise. He is such a happy, easy going boy. I thought Capri would befriend him, but instead she be-mothered (or be-smothered) him!! It took several months for the instant terror he felt when he encountered Capri to subside!
We also got to babysit Krew for a few hours one day and had an absolute blast. Again, Capri did some mothering/smothering, and surprisingly Max is the one who seemed to love it the most. I thought Max would play with him for a few minutes and then move on to more exciting 9 year old stuff, but instead he stayed with him for an hour and a half. Max wanted him up in his bedroom, so Krew could watch him build Lego creations. Max even made a comfy and safe little nest of pillows for Krew and propped his head up so he could see. It was quite endearing.
