Q: What can I do to hlep my toddler develop language skills?

Answer: Name objects in the house, talk about things like the weather and let your child know where you are going. This will encourage them to respond. Listen when they talk and repeat what they say (eg.: "Yes, that is the cat") to reinforce their learning and teach them about communication.
