Normally, children begin to control sphincters first during the day and later at night.
Once you can perfectly control the pee during the day, it will be time to try it at night.
Above all, the child should feel confident, because it is not a matter of hurrying the diaper and then wet the bed every night because he was not ready yet.
As it happens when it is time to leave the day diaper, it is they themselves who start to give us signs that it's time to leave it to sleep too.
They say it is advisable to remove it when they get up for a week in a row with a dry diaper. I would say more, about 10 days or 2 weeks and go see how the little one takes it. It is not a mathematical rule.
Every day they get up with a dry diaper, celebrate it, mark it on a calendar and after a few days tell them that they can try to sleep without a diaper. You can place a mattress protector or a towel under the sheets just in case, because it will surely slip several times. It's normal and we have to let our son know that nothing happens because of that.
Another sign that it is time to try to remove it is when they begin to find it uncomfortable to sleep with a wet diaper.
One tip is to put on a pair of diaper panties when you go to sleep that are no longer like baby diapers, but if the pee escapes, nothing happens. Maybe it is the child himself who begins to wake up just wanting to pee, that would not give the pattern that it is a good time to remove the diaper.
Nothing happens with going back. There will be parents who may not agree with this, but I am one of those who believe that it is not a contradiction to remove the diaper from the night and if we see that it is not mature, put it back on.
Keep in mind that leaving the diaper does not only consist of controlling the sphincters but also has a great psychological ingredient.
As the psychologist María Paula Cavanna says, we are talking about children of 3 years, not 10. It does not mean a regression, but a support until they feel more confident. More frustrating for them than using it again would be to remove the diaper and have them bed every night.
Needless to say, you should never scold them for peeing in bed. It is normal to happen from time to time, there are nights where they sleep very deeply and it is common that with 4, 5 and even 6 years they escape some night.
