If you are concerned that your day-trained little one is still in nappies at night, don't worry. Just because a child is dry during the day doesn’t mean they should be automatically dry at night. Night-time toilet training is quite different from daytime training, and many children take quite some time to be dry at night – sometimes up to 2 years for super-sleepers.
On average, the majority of little ones are around 3.5 or 4 years of age before they are reliably dry at night. However, some children do still need the safety of night-time pants or protective covers at the age of 5 or 6 - mainly down to being very deep sleepers. Of course, some children with medical conditions may go beyond this age.
Even if your child is dry at night from an early age you may find they have the odd accident. This is normal and nothing to worry about. Even older children have accidents occasionally, caused by illness, nightmares or over-tiredness.
