Timed checks help, and no harm showed up at age six
Researchers in Melbourne taught controlled comforting or camping out to parents of babies with sleep problems at 8 to 10 months, then followed the children to age six. They found no difference in behaviour, sleep, stress or closeness to parents.1
The 225 children followed showed no lasting effect, good or bad, from the sleep help their parents got.1
babies' sleep problems cleared within two months with controlled crying, against 36 of 76 without it. Their mams' low mood lifted too.2
of 52 treatment studies found that changing how a baby settles helped, in a review for the American Academy of Sleep Medicine.3
Gentler methods have fewer trials behind them. In a small 2022 trial, a responsive method matched controlled crying on sleep and those mams were less stressed.4 Bedtime fading cut the time to fall asleep as much as controlled crying in a 2016 trial.16
The HSE and the Lullaby Trust give every family the same safe sleep rules
- On their back, in a clear, flat cot or Moses basket.Keep pillows, bumpers and loose blankets out of it.9
- In your room for at least the first six months.The HSE and the Lullaby Trust both say this.89
- Never fall asleep with your baby on a sofa or armchair.The risk of sudden infant death is 50 times higher there.10 The HSE says not to share a bed with a baby under three months, or after alcohol, smoking or drowsy medicine.8
- Night feeds are normal for months.The HSE and the Raising Children Network start sleep methods at six months.711 The five Irish consultants who gave an age start at four months or later.17
