Sorry I have to post again my iPad is glitchy.
To continue, it is imperative that navel is sprayed with iodine, and yes tube some colostrum in, if you hve a baby bottle perhaps you can try it with a small lamb teat if you have one, perhaps lamb will take that but otherwise Please do a little research to tube as you could get the wrong hole. Don't let lamb get too warm either but make comfortable and some time on your lap would be a good idea. Good luck
