I have a spanish goat that had a kid soon after I got her, she fed the baby the first 4 days. But after that we have to hold her so the little fellow can nurse her. She is getting harder to catch each time in order to feed him. Thank you for any help!!

Here's something on the topic I found:

Once in a while, you’ll have a doe that simply won’t let her kids nurse. Maybe her udder is painfully tight. Maybe she’s a new Mom and hasn’t figured things out yet. Or maybe she just decided she doesn’t want to be sucked. She’ll whirl away from the kid that’s trying to find the teat. Maybe she’ll bite or butt the kid, paw or kick at it.

Sometimes you can tie the doe to the wall and shove her body tightly against it to immobilize her while you help the kid to nurse. Often, if you do this several times, then offer the doe grain while supervising the nursing, she’ll reluctantly allow the kids to nurse.

But once in a while, a doe simply won’t let the kids nurse and you’ll have to bottle feed them from the start.
