Newborns questing in the wrong place... Depending on how much time and patience you have at the time, either top it up with colostrum (from the ewe if you can) to give it strength and you peace of mind, then leave it for several hours and see how it's getting on, or sit with it, gently guiding it to the right place. It'll fight if you try to force it, so it has to be patient and gentle. Try putting the test in its mouth, squirting a little milk in its mouth, and so on. BH is incredible at this, but then he's had 50 years' practise. I'm getting better, but still sometimes have to decide to top it up and walk away, because I'm getting frustrated and there are other sheep to see to.
Some people don't like to give a newborn a bottle, saying it interferes with it developing its ability to suckle from its mum. Personally, I've never found this to be an issue and I must have topped up a hundred or more over the last 10 years.
