That's what I thoughtIs her udder or half of the udder hard and hot or just full of milk?
Without being there to check her in person, my guess is that he nursed down the one side, but the other side is full and uncomfortable and she's not letting him suck because it hurts.
I'd milk out that side a bit to make sure everything is ok. I'd also get him latched on to that side. Some single birth lambs have trouble figuring out the "2 sides to the udder" thing.
