Speech delay. Therapist. kindly guide.

Hi, I have a son who is close to 3yrs old. He speak very few words which includes fruits, vegetables, color,animal and animal sound, two rhymes partially, he follow my words, numbers upto 20, few shapes name as well but he don't say mama as in to call me. One more thing he will say these words if I will show him and ask what is this but not if I ask him do you want apple or banana or do you like blue or orange colour. He won't reply. He won't call me if he want me to go to bedroom instead he will hold my hand n he will try to pull me. If I ask him to say the word he will get irritated and start crying or he won't find the word interesting enough to say. What should I do. Is it really a situation where I need to go for speech therapist. Kindly guide. Thank you in advance.
