Bedwetting is strongly hereditary, which means it is very common for me to see two siblings in the same family who both wet the bed. The question that comes up almost every time: do we treat them at the same time, or do we go one after the other? There is no single right answer, and I walk parents through the tradeoffs.
The case for treating both at once
When two siblings start the programme together, a useful dynamic often appears. The children see each other working at the same goal. They compare notes, they cheer each other on, and the older one usually wants to be the first dry. That motivation is real and it speeds things up. The other practical benefit is the timeline: instead of nine months of treatment running back-to-back, you can complete both children inside the same four or five-month window.
The case against
The first weeks of treatment are demanding for the parents. The alarm fires, someone has to get up, change sheets, walk the child to the bathroom. With one child this is hard. With two, on the same night, sometimes both alarms in the same hour, it can be punishing. The other downside is the cost. You need two alarm devices, and that doubles the equipment investment up front.
How I decide
I look at three things. How tired are the parents already? If the household is running on fumes, one at a time is usually wiser. How motivated are the children? Two engaged children carry each other through. One reluctant child paired with one motivated sibling can be a drag on both. And how big is the age gap? Two children within two or three years of each other usually do well together. An eight-year-old paired with a five-year-old often does not, because they are at different developmental places and one will outpace the other.
The staggered option
If you decide to go one at a time, start with the child who is more motivated and more ready. The first treatment takes three to five months. When it is done, the same alarm can be reused for the second child without missing a beat. The second sibling has the additional advantage of having watched the first one succeed, which is a powerful motivator.
Either path works
Both children can become dry. The choice is logistical, not clinical. Pick the version that fits your household and commit to it fully. Read more in our FAQ.
