Helping all children become happy learners

Social Interaction and Play Milestones


All children develop at different rates and so reaching milestones slower or faster than peers does not necessarily mean that there is reason for concern. Differences of up to 12 months are very normal. However, it can help to identify areas where a child may warrant some additional support particularly when more than 18 months off a chronological milestone.
