Question about achieving focus for portrait while shooting wide open?

Using a 5DM3 and a EF 24-70mm 1:2.8 L I'm taking photos of a toddler holding a newborn on her lap. The toddler's head is just above the newborn's. I'm using natural nearby window light (not much) so I am shooting wide open at 2.8 and have my ISO somewhere around 500-600.

The issue is that I use the focus point to focus on the toddler's face, though the newborn's face becomes soft and out of focus. Is my only option to increase the light and just close my aperture?

If so, what do you do if you still want to add some blur to the background but need to close the aperture?

Thanks.

That's the simplest way. Also try to keep both sets of eyes in the same vertical plane.

If so, what do you do if you still want to add some blur to the background but need to close the aperture?

2nd simplest would be to increase the background blur in post-processing. Most other solutions would require a lot more work.

With practice, you'll be able to get both sets of eyes in focus at f2.8; it's all about getting them on the same focal plane.

In this case, if you raise the camera up and tilt it downwards, you'll reach a point where both faces are the same distance from your camera.

OR... Embrace the tighter apertures. You can control your background with light as easily as you can with your f-stop. Put your subjects close to the window and let your background fall into darkness. Lots of options to isolate your subject.
