Children need to be added to the padron (short for empadronamiento) so they can be enrolled in school, access healthcare etc.
Proof of address does not need a time span, simply proof that the child is living with you.
Obviously passport, probably birth certificate. Do you have TIEs? A NIE is only for those over the age of 18 but they do need a TIE or, if from the EU, also registered on the EU foreigners register but do not need the fingerprint test if under 5 for the TIE.
6 weeks seems a long time to get an appointment for something like this. Spain is very good at making you get so many documents, prove things but not having the facilities or manpower to do so. They seem to have enough tax inspectors if they think you are getting away with something but making rules to do things in a certain amount of time (such as TIE renewal) and then making it impossible to do so seems the norm here.
