It does sound it, Mom2LOL. Especially w/ a history of supply issues, it's great you're aware of it. Wonderful news about it kicking up w/ some extra food/water.
I liked keeping Larabars, Clifbars, and Luna Bars around the house when I was bfing the kids exclusively. I also still drink and Ensure a day. I can bring you a couple to see if you like them. An regular Ensure gives you 250 calories. For me I've always had a hard time finding the calories I need. I know bars and ensure isn't the best option (over REAL food,) but for me it has been what works. (keeps me surviving.)
I keep 2-3 16 oz Nalgene bottles full of water around the house (on the couch, by the rocking chair, and kitchen table. That way, a water bottle is almost alway within reach.
So very thankful for all "the moms." You ladies give me strength.
