Yup, I had two baby pigs as a surprise, and I agree with what everybody else has said. They were terrified of me. When you expect them to be adorable, cuddly lap pigs, and they spend the first two months (and often longer) actively avoiding you, it's very tough. You have to work your butt off and even then you can't guarantee they will instantly become cuddly or happy to see you- or anything else, really. Plus, they're only "cute adorable babies" for about a month or two after getting them; after that, they're bigger, with a lot of growing left to do but they've ultimately lost their "adorable baby"-look. THEN you're stuck with an adult-looking young pig who's terrified of you, not withstanding the puberty tantrums that you have to go through, both towards yourself (my two boars can be very grumpy!) and each other (.. again, the amount of times they've been bickering recently..)
Having said that, if everyone here cannot dissuade you from a baby, I would advise please be patient and wait until one becomes available. The RSPCA regularly take in pregnant sows- I know there were a few in Birmingham when another UK-goer enquired- so please be vigilant!
