does your baby only like one brand of pacifier?

My son has only liked nuk pacifiers since the day he was born. I've tired different brands mainly because they were brands we got at our shower and I toss his pacis every few weeks(and we magically lose so many). But today we tried Dr. Brown's pacis because they were on clearance at Walmart for a freaking $1 so I was like no harm in trying, at least I won't waste much money if he dislikes them. He actually likes the Dr. Brown ones!! So, now he has two brands he likes lol
