I used to put the meat/meats on the grind button of the blender for a couple of pulse hits to moosh it down so it was not actually a paste but had some substance. ChowPup grew up to be 6ft 5inches and cuts his own meat now! Good luck.
Well done bacon, so that it crumbles into little pieces when baby chews it, and it's easy finger food. I second the boiled chicken/soup chicken. Lox is also a good soft food (okay, so it's fish, not meat, but it's still protein).
