I found a great website that has great time saving tips for moms! One I'm listing here is very simple:
Have a staple shopping list
You will want to check out Family Education and the staple shopping list found there. When you access some of the resources there, they request you enter your email address. Take a moment and look at the list of newsletters below the fill-in box. You may want to un-check some or all of them so your inbox isn't full of emails from them.
I can testify that staples are sometimes the things I most easily forget - mostly because I assume I always have them on hand! Take ketchup for example. It often doesn't make it on my shopping list, but eventually I run out right in the middle of a recipe that calls for it. Having a staple shopping list with you all the time helps you to do a mental check of those items AND helps you to notice them more readily especially if they are on sale (it never hurts to stock up!).
