Aw, first time assessment can be nerve-wracking talaga! The developmental pediatrician (devped) will usually do observations, ask you about your child's milestones and behavior at home, maybe some screening questionnaires, at times physical check-up din, it's really just to get a clear picture of how your little one is developing so they can give you the right guidance. Dala mo lang ang any videos or notes you have about the behaviors you're concerned with, and just be honest sa kanila about what you're seeing kasi they're there to help, hindi to judge. One of my mum friends said she brought a list ng specific examples and it really helped ang doctor na ma-assess better, good luck bukas, mama, kaya mo yan!
