Found kitten in greenhouse

[yandere]

So, one of our barn cats had a litter a 2-3 weeks ago, anyways. One of the kittens must have wandered into the greenhouse, or was left there when the mother moved them when the rain stopped, what ever happened, I found her stuck between the wall and the pool we have in there for growing saplings. I wouldn't have known she was in there if she hadn't been yelling. I'm not sure how long she'd been in there, anywhere between 2 days to a few hours. When I reunited her with her mother she started nursing pretty quickly. I'm just wondering if there's anything else I should do, I don't want to risk her being neglected because I took her to a vet as it seems that she hasn't been weaned yet.
