Development plays a big part
Crawling, pulling up and separation anxiety can all increase waking and bedtime resistance.
Routines become even more important
A predictable day and bedtime often help babies feel more secure during this stage.
Avoid dropping naps too quickly
Many babies still need solid day sleep to manage this age well.
Important: baby sleep varies enormously. Avoid one-size-fits-all promises, and always prioritise feeding, growth and safe sleep advice.
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.
