Baby & Child Sleep Needs Reference
Total sleep, night vs naps, by age — the NSF ranges with the spread acknowledged.
The ranges are wide because real babies are — a 12-hour sleeper and a 15-hour sleeper at six months are both normal, and chasing a chart against a happy, growing baby helps no one. What matters clinically: dramatic changes from the child's own pattern, or breathing pauses/snoring, which are paediatrician conversations.
