It is too early to judge your child's language development. My child has her assessment at the mother and baby clinic after 4. For language assessment, you may have one as early as 3 at a govt clinic, though you may make it earlier if they let you. However be expected to wait for one year after you've got the assessment. I've decided not to wait and found a private speech therapist. I've found that 4 yrs old is just the right time for my child to have therapy, though your case may be different. If you suspect anything, don't wait for the govt, go for a private one. For motor skills assessment, you'll have one when your child turns one. Sometimes their assessment can be too difficult for your child, as I've found different govt clinics have different tests and the levels can vary a lot. There are lots of baby health web pages with baby development for your reference. Talk to other moms to see if their children have the same problems.
