The lamb is usually sucking away within an hour or so. If the ewe is going to have twins, she will stop licking and cleaning the first lamb to concentrate on pushing the next lamb out. The second one usually comes much faster than the first.
This ewe had a nice big single - but not too big to cause birthing problems. When I arrived, the lamb was up on its legs. The bag that is coming out of the back of the ewe is part of the birthing process. It comes out after the birthing is done. I do not know what it is called. Perhaps a sheep person out there can leave the proper name in the comments.
The following are some sweet photos of the ewe and the lamb bonding. You can see that there is another ewe paying attention to the lamb. That ewe was close to lambing - they frequently try to steal a new lamb from another mother.
The ewe will lick the underside of the lamb's tail. That stimulates the lamb to nurse. When we are caring for bottle lambs, we frequently tickle under the lambs tail to stimulate the lamb's sucking reflex - just like the mother does with her baby.
Here the lamb is having it's first drink. Successful bonding and drinking! That is what a farmer wants.
Hope you all are staying warm and having a nice week.
