Does having motor tics as a child have something to do with poor motor development as a toddler?

No. Most tic disorders are independent of other neurological problems. Tic intensity usually peaks by age 10 years and then seems to subside. There are occasional associations with underlying neurological diseases.
Not necessarily. Tics and motor incoordination are generally not related. the two may coexist. However there are motor disorders that may present with tic like movements, so raise this issue with your pediatrician.
Some children with. Tourette syndrome have mildly low muscle tone ( resistance to passive movement) & fine motor/ graphomotor delays. Depending on the etiology of the tics, as a general rule, a child with one neurodevelopmental disorder has a risk of having others along with it.
