sign of a smart baby?????

Mom, is it true that an active and rarely sleeping baby is a sign of intelligence? My child is really difficult to get to nap... they want to play, read books, play with Lego, and similar activities... they also can already show what they want quite well. According to the doctor, their speech development is quite good for their age. Many people say my baby is smart... but I'm actually worried about their growth because according to sources I've read, sleep is very important at their current age 😢
