Speech & Language Milestones

DEVELOPMENT GUIDE

Speech & Language Milestones

A guide to typical development from birth to age five. Every child develops at their own pace — if you have concerns at any stage, the best first step is always a conversation.

Please note: These milestones describe typical development — there is natural variation in when children reach them. If your child is not reaching several milestones in a range, or you have any concerns, please get in touch for a free, no-obligation consultation.
