how to encourage (more) my toddler to speak, he's turning 3 this year and all he can say is the colors, car, bus, etc. mostly one word. my husband refuse to consult a speech therapist.

How did you interact with him when he was younger? Did he always get the chance to interact with people who would usually talk to him? You have to consider the factors on why there is a delayed in speech. If he was left with a nanny, you also need to know how the nanny was to him while you guys were away. At his age, it's best to consult a specialist. I have some friends with kids who have speech delay. The most common reason is when the kids were left with the nanny, the nanny usually puts them to sleep so she could do something else. There's not much of interaction majority of the time on a day-to-day basis.
