Sitting

-Place a "Boppy" Pillow or a pillow behind your baby (and on either side of them if not using a Boppy) for support.
-Place a "tall" toy in front of them to bring their eye gaze up
-Place a toy that is easy for your baby to activate and that interests them in front of them (you can place another small pillow on your baby's lap as a sort of "table" and place the toy on that pillow)
-Have your baby sit with their back against the sofa and pillows on either side of them for support, with a toy in front of them
