Ladybugbo, if you buy the food maker she can just toss it on the appliance again frozen and it thaws and warm it at once, if not then you can always microwave it, alwasy make sure you check in case is to hot to feed Cash, wait until it cools off. I have one of those spoons that ells you by changing colors when the food is too hot for baby.
How do you thaw the food? Do you lay it out the day before or use warm water?
Ladybugbob- Have you tried when you are home making big batches of food for him, and then freeze them I found on WIlliams and Sonoma a great baby cook appliance named Beaba,haven't used yet because we are still working on cereal, but it suppose to be really easy to make baby food, it steams and blenderized on the same appliance so you dont have to use more stuff in your kitchen I know is a little bit expensive 149 or so, but is totally worthy and specially for working moms like you, maybe when you come bck form work at night you just chop things up and toss it in the baby food maker and within minutes you have a huge batch of food you can freeze and then just thaw it before feeding him.
I will suggest you use Gerber Organic food, I have heard good things about them.
