Teething ?!?

Melissa

So my baby is 9 months old and only growing 1 bottom teeth so im wondering if this is normal?? I keep seeing delayed teething can be because low of calcium?!? What can i do? She drinks abt 24oz of formula every day and has some purées, baby oatmeal, & im scared of giving her other food since she doesnt have any teeth im afraid shes gonna choke or something.
