Infant crying and sleeping after 3-4 months

An in-depth guide

Caring for an infant can be rewarding, but is sometimes challenging too. This guide focuses on managing infant crying and sleeping from about 3-4 months of age. A guide to coping in the first few months is also available, you can access it here: Help with young babies

Except where health or safety is involved, this guide does not try to prescribe the best way to look after an infant. Instead, we aim to provide information which helps parents to choose care methods which suit their baby and themselves. The suggestions here are all based on research evidence about methods which have helped parents to manage. Some of them may work for you.

The superscript numbers e.g.[1] inserted in the text below identify the original research studies which provided the evidence. They are listed on the Cry-sis website: Infant references

This in-depth guide is produced from a paper by prof Ian St. James Roberts, a patron of Cry-sis, gives detailed information and advice on crying and sleep problems, together with references for further reading.
