Right of the husband as a guardian of his newborn baby

Hi.

I am separated with my wife for the past 3 months and a case is ongoing in the family court. She and her father are not disclosing her delivery date.

Whenever I ask, they say that they don't want my kid to call me father and I should not see my kid after delivery.

What to do in order to get legal support and know the delivery date of my wife?

Her father is the one who blocks getting information.

Please let me know what to do.
