Problems in speech

Hi co-mommies, I'm worried po sa toddler ko na 3yrs old 1 month. Since hindi pa siya nakaka-straight ng isang sentence pero he can talk naman one word at a time. I will take suggestion and opinion from other mommies here sa Asian parent, or recommendations ng speech therapist near makati and how much it would cost per session po. Worried since he's going to preschool na next year when he turns 4. Thank you! #firsttimemom #advicepls #firstbaby #pleasehelp
