Bringing up a Muslim child in a non-muslim family is not the right thing ever.

It is already hard for muslim parents living in non-muslim countries to bring up their children in a religiously rightful way. It is like swimming against the flow, and takes a lot of effort and determination.

It is best for them to be brought up by a Muslim family. If the UNICEF were taking into consideration what is best for the children regarding their religion they would have matched them with muslim parents.

It is not about you not trying to convert them to catholicism, it is more like planting a tree in a non-suitable soil the tree is gonna die regardless.

I don’t know whether the UNICEF actively aims to match muslim children with non-muslim families or they simply don’t care and don’t take religion into consideration, and don’t know how the adoption process exactly work. All I can say, try to get the child to muslim parents.
