I had two doe under the yard feeder a few days ago. It was mother and child, and the fawn spots were gone. The 'child' was shoving mom off the corn, or at least trying to, and then the not-so-little one wanted milk and started bumping mom in the udder pretty hard. And then he got milk.
Three years ago we had twin fawns in the yard. They were inseparable, and hung out together the following year. One was a budding buck and the other was a doe, and they were together till the rut. After the rut, here they were again. Pretty sure it was the same twins. About the last time I saw them, he still had his antlers, and I remember the weather was pretty warm. He had some corn at the feeder, then slowly strolled into the front yard and got down on his belly and hung his tongue out and appeared to be relaxing. Here came a doe, which I am totally convinced was his sister. She looked for corn, which I guess he had eaten, then she briskly walked directly to him. They touched noses and then she kicked him hard and made him get up. Then, off to the pond she walked, with him right behind her, with his head hung down. Bossy sister, just like humans.
