count to ten

It really depends on each child, so don't be too caught up with milestones! My son is 2 years old this weekend, but he only knows "mama" and "mummum" - and yes, he has isolated speech delay (diagnosed by assessment) so it'll take some time for him. He is able to understand things way beyond his age, but he cannot find the right words to use to express what he wants - so simple milestones like this would be hard for him to manage by the "standard" milestones.
