Need advice

Most people have the possibility of getting type 2 diabetes and those who are related to or, indeed, live with people who have a diagnosis are at greater risk. The "live with" bit seems a bit odd, but this is because families tend to have a similar diet and a diet with too much sugar/starch/carbs in it, leads to T2 diabetes in the susceptible.
As far as I am aware, you have no more need to worry about Baby than the next mother. Make sure that the whole family eat a healthy diet, not too much processed food and avoiding sugary drinks, biscuits, sweets and so on. Make sugar a treat, not the norm.
Knowing the symptoms of diabetes, you have a big advantage over most people: If there ever is a problem, you will recognise it.
My very best wishes to you and Baby.
Sally.

If you are worried about T1 the signs are:
Thirst - drinking a lot
Thinner - dropping weight
Toilet - a lot of urine and
Tired - no energy
