What often changes at one year
Development, separation anxiety, teething and early attempts to drop naps can all affect sleep.
Keep two naps if needed
Some one-year-olds still need two naps. Dropping to one too soon can backfire.
Bedtime may need adjusting
As naps shift, bedtime sometimes needs to move a little earlier or later.
Important: every baby's sleep is different. Avoid one-size-fits-all promises, and always put feeding, growth and safer sleep first.
Safer sleep reminder. For babies, use a firm, flat sleep surface and follow the latest safer sleep advice from the NHS and The Lullaby Trust.
