Dependent upon sign language?

My daughter says what I think is a “normal” amount of words. However, she uses A LOT of sign language. She even makes up her own signs. She never tries to speak the words that she signs. I’m not sure if she uses signs because she can’t say them or what. Her comprehension is great, I just worry about a speech delay? She tries to say words and they come out jibberish.

She can speak:

Duck

Cat

Dog

Black cat

Bye-bye

Pop pop

Daddy

Mama

Snack

Banana

Hogwarts 🤦‍♀️

Car

Eat

Hot

Hot dog

Hat

Sock

Cup

Water

And she can make most animal noises.

She signs:

Help

Poop

Pee

More

Fish

Pig

Potty

Hi

I love you

Lovey

Elephant

Sleep

I’m just not sure if I should be concerned.
