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 plenty of daytime sleep at this age.
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.
