Teething Timeline Reference
Which teeth come when — the eruption sequence with the wide normal ranges that calm 3 a.m. searches.
The full range is enormous — first tooth anywhere from 4 to 15 months is normal, and a first birthday with zero teeth warrants exactly nothing but patience (a dental check by age one is recommended regardless). Sequence matters more than timing. Teething causes drool and chewing; high fever and diarrhoea are *not* teething — those get treated as illness.
