Really could use some advice (sorry long post)

So my family ASKED if they could take my 6 month old daughter to their house to spend time with her. My husband and i say sure no problem, we send her off with a bottle and baby food as back up in the rare event she got extra hungry. I tell my family "make sure she gets a nap around 3:30 or she will be really cranky." (my family looks at me like i have 3 heads when i tell them our daughter has somewhat of a schedule that actually keeps her happy). They blow me off, make fun of me for "making" her take naps, then proceed to disrespect our request & keep her awake for 5 hours straight. Fine, whatever. So then i get a phone call with my poor baby in the background screaming bloody murder because shes tired,  with 5 ADULTS in a panic insisting that my daughter is "starving" and that i didnt give her enough food, im a horrible parent, & threatening that "if i pull that shit again i will need to find a new babysitter". 

WHAT?! 

#1 you ASKED to take her home. 

#2 she had plenty of food

#3 she hadnt had a nap in 5 hours

#4 take a look at my baby, does it look like we starve her?!

So we come pick her up, i go to feed (cuz remember, shes "STARVING!"), & the girl eats for literally 1.5 minutes & completely passes out on my boob  due to pure exhaustion. I am so pissed off that they put her through that! Now a week later & they STILL dont believe that she was crying from being overly tired. They keep bringing it up, yelling at me, talking crap behind me and my husbands back. They have our baby for a few hours and instantly they are baby experts & we are the idiots who apparently know nothing about our own daughter 🙄🖕

What the eff?! Am i out of line for being completely livid at how my whole family is acting? Do you have any advice either: 1) are my husband and i wrong? Or 2) how to handle my family's actions?
