DePaul says 14 babies were born into its service last year.
In its annual report, the charity says it helped more than 7,400 people facing homelessness.
More than a fifth of those are under the age of 18.
DePaul is calling for urgent action from the government to stop what it has labelled "intergenerational homelessness".
Today we are launching our 2022 Impact Report!
Last year, we supported over 7,400 women, men and children - a twofold increase on 2021. Whilst we are proud of the life changing work being done, this increase highlights the importance of tackling homelessness in a radical new way. pic.twitter.com/IJxXlYPzYL

CEO David Carroll says growing up homeless can cause issues later in life:
"The issue of child homelessness is considerable," he says.
David says not having a "stable friendship group" around a child, because they're in emergency accommodation, has a potential impact on development going forward.
"Research shows they're more vulnerable to developmental delay."
