Not saying much

Am

Anyone else’s little not really saying anything? My son makes noises but not really sounds. He will say “mama” when he’s cranking but that’s it. My niece is 12 days older and repeating lots of words, she said auntie/kitty/daddy when I was visiting. My son is fully walking now, he is ahead of schedule with motor skills but wondering if he’s behind in verbal. I honestly don’t remember when my first son started talking
