Query about toddler


Hi all. My lo is 19 months. She says few words thsts all but doesnt talk yet. follows simple commands. Knows 2 body parts. She doesn't know animal sounds, shapes and colors but can sort out shapes. Is it that she can learn colors and sounds n body parts only if she talks and understands what we talk. Iam trying to teach her. Sorry if this is a silly question. TIA
