Visa process for Indian baby whose parents have China residence permit (Z type)

My name is Hari Krishan Raina & I am Indian Passport holder (Z2530352).

I am having a Chinese residence permit (Z type) & working for Airbus in PRC. Currently I am in Spain for one year assignment which will complete by 31st Jul. 2016.

Support needed: I am expecting my baby to be born in mid-June & would like to know what category of entry permit I could apply for him. As per my discussion with one of the agents in PRC, they suggested that I apply tourist L type & then convert it to residence permit once I land in PRC.

I would need your support to know what process to follow & what documentation do I need for his entry permit. Appreciate if you could guide me here so that I could prepare some documentation in advance.

Thanks in advance for your support & clarification on this topic.
