OK well I don't like to shock you but it looks like one of those studio photos taken after death
The reason why I wondered is because the lady is in black & the child looks rather stiff & her eyes look slightly odd.
There is a site with photos of these but as they are very upsetting so I won't put the link up here, pm me if you would like it.
In North America in particular, if a child died the family would sometimes "stage" a last photo with the deceased, they would sometimes be kept upright on a stand, & they would paint "false" eyes on the child's eyelids. Sorry it's really morbid, but look at your photo very closely. The child's arms are very stiff don't you think? The photos were called memento mori.
However of course it may be a completely normal photograph so excuse my barking up totally the wrong tree lol!
