This timeline only provides a very general and brief outline of expected developments from birth to age five, individual children can still exhibit varying development patterns as this timeline only serves as a general guideline. This timeline is only one model, other models regarding language development exist.<ref name=":5">{{Cite book |title=Language Development: An Introduction. |vauthors=Owens RE |publisher=Pearson |year=2005 |location=Boston |pages=125–136}}</ref> The development of language remains a theoretical mystery.<ref>{{cite journal | vauthors = Taylor CM | title = An examination of the development of language in the normal child | journal = Journal of Child Health Care | volume = 3 | issue = 1 | pages = 35–8 | date = 1999 | pmid = 10451332 | doi = 10.1177/136749359900300105 | s2cid = 40542310 }}</ref>

Based on the milestones set for typical toddlers, if the child tends to have a lot of or very long delays, they may be deemed as having language delay. However, proper testing by a professional like a speech therapist or a doctor's confirmation will be required to determine if a child has language delay. Although these milestones are the typical milestones for a child, they should not be followed strictly as they are mere guidelines.
