With plastic storage, there is always the concern about expense, the harm to the environment, and exactly what type of plastic is used in it. If you can recycle, that is much better. Someone suggested putting recycled jars in the dishwasher to get clean, which is fine, but always remove the labels first (soak in warm water). If you put it through the dishwasher, the label can wash away or disintegrate, but the glue can get stuck in the jets. I used to do this and after a while I noticed the dishes weren't getting clean. Then it cost me a lot to have the appliance repair service clean out each hole in the jets so that the water could get through!
I think it helps to put the cooking time on the side of the container or just tape that part of the box to the lid of the new container. I don't see any reason to transfer pasta from the box to another storage container unless you are displaying things on the counter. Things in bags (rice, lentils and so on) can be easier in a storage container although I just close the bags by rolling the top down and wrapping a rubber band around it. HOwever, with a small child, that may not be childproof enough to keep rice from being scattered all over! That's up to you.
As for new ideas for earning income, I have a home-based business with a top-ranked company with an extremely generous and ethical compensation package. If you enjoy helping others and want income every month, you need to check this out. I work part time but my check gets bigger every month! A lot of moms do this business but it can be done by anyone - no special background is required. The company-provided training and support is excellent and free. Feel free to contact me for more info. We can do a 15 minute phone appointment to see if it is right for you.
