My son is 2 yr 10 months old & he is not properly talking. He speaks only single words. Can you suggest me what should I do?

Chill ka lang mommy.. Yung anak ng friend ko ganyan din tpos 3 years old na. Ang ginawa nya, pinapasok nya sa school and ginagala sa park pra may nakakausap din syang ibang mga bata.. Ngayon onti onto nakaka salita na :)
