No, it would have too much added sugar and spice.
You can get cans of plain 100% pure pumpkin at the store. It should just list pumpkin in the ingredient list--no spices or sugar or eggs.
You'd just need a small amount each time for your little ones, so you'll probably need to freeze most of it--it only keeps for a little while. I think growler said she's frozen plain pumpkin in an ice cube tray so that she could separate it into pieces and only thaw one at a time when she needed it
Just bring a piece to room temperature and add it to the youngsters' food.
