1 nap or 2?

My beautiful toddler is confused about whether she needs one nap or two and it is confusing me! Most days she takes 1 nap just after lunch and manages a good 2 - 2.5 hr nap during that time, but the last few days she has begged for a morning nap. She follows me around holding my legs saying "hold you" or "night-night." I have given her the nap when she asks, but I don't know what is best? Maybe she is fighting off being sick and will go back to one nap in a few days? Why are toddlers so confusing???
