Please Tell Me I’m Not Going Crazy Or At Least Make It Make Sense

If A Mother Of 4 Boys Wants YOUR 1 Year Old Daughter To Spend The Night Over Her House Is That Not Idk Weird Or Some Sort?? Also I Have Been Told By The Mother In Law (Which Is The Mother Of 4 Boys Mother) That When I Leave My Daughter In Her Care She Doesn’t Watch Her At All My Child Has Even Came Home With Knots On Her Head, Her 5 Year Old Sons Like To Wonder Off With My Daughter He Also Ruffs Her Up & Hit Her AND THE MOTHER SAYS NOTHINGGGG… The Grandmother Claims/exaggerates that she “Seen Something in the spirit/dream that she could not speak on happening to my daughter” the only thing I could think of is possible Sexual Assault from one of the kids idk… LASTLY, the grandmother doesn’t let my daughter spend the night at her daughter house (mother of 4 boys) Alone is that not alarming of some kind???? YALL WHAT WOULD I DO?? I don’t want anything to happen to my daughter, I wouldn’t be able to live with myself if my daughter got molested etc!!! She also LIES FOR HER SONS, she tries to take up for them for example if her 5 year old son put on knot my baby girls head and dropped her SHE WOULD LIE AND SAY SHE FELL!!!!
