Here's a video of my grand daughter and I signing the song
On Top of Spaghetti.
She is 19 months old and communicates through voice and signs.
You may notice that some of her signs do not match mine and that is because her fine motor skills are still developing.
One example is the sign for 'spaghetti'. It is made using both baby fingers but she uses her thumbs.
As your baby begins to use sign you will recognize how they sign each word.
