How often should your baby be moving?

Jamie
I'm 23 weeks and I noticed my baby moves a little less. He still moves and kicks but idk why I feel like it hasn't been as often. Is that normal? At first he was so active but now he seems more laidback. I still feel him move everyday so it's not like I'm rushing to the ER with concerns but I was just curious if that is normal? Is it some kind of growth spurt?
