Until 12 mo (or in your case, probably 15mo, since most babies will 'revert' to a total milk or formula diet after stress/illness/surgery for 2-6 weeks depending on severity)... solids AFTER their milk or formula, OR when you need them distracted let them play with mushy finger foods / take nibbles from your plate. :) :) :)
There's just not enough nutrition to support the massive growth they're going through in table food... but table food will fill them up. Consider table foods like cake. It's DELICIOUS. And you WANT it, can even live on it for awhile, but it's not what your body needs.
4 more months at a minimum of primary nutrition = milk or formula, and probably 5-6 because of the surgeries.
