Hi Lateisha! Congratulations! Have you been to the pet store or your vet yet for advice? They'll let you know about proper nutrition. Although Mom and Dad will do the feeding, they may recommend supplements.
Keep drafts away from the cage. If it's near an HVAC vent, the temperature difference of those breezes could be detrimental.
Mostly, think of it as being a grandparent. Let the parents do the heavy lifting. You just provide a safe cage with healthy food, kick back and enjoy!
Btw, you're doing a great job!!! Birds who aren't happy, won't breed. :)
