Was I in the wrong??

So my boyfriend mom feel some type of way about me telling her that - I don’t want company all the time because I be tired from not getting sleep through the night because I breastfeed baby & deal with my other two TODDLERS . So she feels I’m tryna keep her from seeing her granddaughter . She’s a first time grandma. And I understand she wants to be around baby , I’m cool with that . No problem . But she calls asks if I’m home and be at my house in less than 5-10 minutes w.o giving me time to get up get myself prepared house cleaned and kids ready for company to be over . I don’t like that . She’s also been having a cold since I had my daughter ( Feb 22nd ) and she stills come over and coughs & tries to kiss my newborn & I don’t say anything directly b/c I don’t wanna hurt her feelings but I have said things along the lines of ‘ if you’re sick don’t come around my kids because I don’t want them sick ‘ OBVIOUSLY that went over her head . But now we had a lil falling out yesterday because I mentioned to my bestfriend sunday how I hate when people call and ask me am I home and be at my house in less than 5 minutes like dang can I Atleast shower first ... my ‘ bestfriend ’ went and told my MIL ( they work together ) that I said she gets on my nerves 😑 so I texted her because everyone was coming to talk to me for her instead of her coming straight to me - now everybody at her job is in the business - & I explained what I said and told her what I meant about needing time to get myself together before company started rushing over & that I’m not keeping her from her granddaughter but I’ll rather have a heads up and Time to get myself up before she came over and she replied ‘ I’ll let y’all do y’all .. I tried!! ’ I didn’t respond . Was I wrong ? Why am I being misunderstood about me just wanting time to get up and have everything & everybody ready before company comes over ??

And now my bf thinks I should just talk to her but she didn’t even take the time to understand where I was coming from and she said what she said so I don’t feel the need to talk to her anymore because I said what I said and meant what I said & if she can’t understand that then thatsher problem ! And she also has a problem w me saying I don’t want my child spoiled 🙄 WOW . I’m not a FTM this is my third child ... I guess once you get to a certain number of children you just have no say so on when who what and where w your baby
