This week on Helpline in Focus, speech pathologist Sonia Bestulic answers all your questions about how your child is speaking including:

•Whether growing up with several languages in the home will delay a child's speech development

•If it's normal for a two-and-a-half-year-old to only string two words together (and how to encourage fuller speech)

•If it's normal for a three-year-old to replace 'g' and 'k' with 'd' or 't'

•If a two-year-old should be speaking more than several words, and whether staying at home all day with only one other person may be holding her back

•Will a four-year-old grow out of a lisp?

•How to stop a five-year-old speaking for a two-year-old

•How to help a primary-school-aged child articulate their thoughts
