I have the same issue. Whenever either of our mothers visit we can't find anything in the kitchen for a week. Good Luck! Accept that she will do some of these things and try to rechannel that into something you need done. Go through the bins of baby clothes and organize those for you for the upcoming year--it doesn't matter if it needs to be done as long as it won't drive you crazy. Ask her to cook some of your husband's favorite "mom" meals for the freezer. Spring cleaning--wash the kitchen cabinets, wash the windows if it is warm enough. Reorganize the sports equipment in the garage, or your husband's tools:). Anything to try to turn this into something productive that won't drive you crazy. Good Luck.
