Too many cooks

There are 3 women living in our house. It is a very tight fit. Believe me. There is a toddler with his mother, maternal aunt and maternal grandmother all on premises. A very tight fit indeed.
The mother and son are back home due to economic reasons. Reasons she is working on and making better everyday. But still....
The aunt is a senior in high school. She is all that. Just ask. Now as a mother that has been here 2x before, this is no surprise. It is to her father. George wants her to remain the sweetheart she has been since birth. That side to her is still there. She just wants to stretch her wings. More than we are willing to allow and more than her brain can really handle. The girl just doesn't see that. She will in 10 years when it no longer is an issue.
The young mother is 21, pursuing nursing and all that entails. She is raising a year old son. Toddling, reaching, learning the meaning of "no" and ignoring it. Cait is learning pregnancy is easier than mothering. So is labor. Priorities are everchanging. Exasperatingly so.
I am middle aged and not prepared to be grandmother on site. The boy is a delight. Devoted to the little poop. Really.
Love my daughters. In all their know it all glory. Really
But I am chief cook and my name is on the title of the house. At least it was last time I checked. This everchanging scene is not what I expected. For that matter, I don't know what I expected.
Surely there is a manual out there. Some wise old crone sat down and in her wisdom wrote a tome for any women 45 and older. Telling how to deal with daughters. How to lead them into a good life, a fulfilling life. One where we don't want to commit homicide before they reach that wonderful plateau.
I am sure I never gave my mother such cause for concern.
