In-laws!!!!

My baby is only 5 days old and my in-laws who live in town have seen him everyday so far. Today my mother in law kept nagging saying he was hungry after just eatting. My boy is a sleeper. The only time ge is awake is changing him and eatting. After she fed him he started fussing and crying and she went straight to hes hungry when I knw for a fact that hes just cold and wants to be bundled up and fall back asleep but she kept on insistencing she was right...every time she fed him she kept saying he needed more when the doc told us that 2 oz right now is plenty. I even told her several times hes not hungry just cold. I even put is snuggle on and instantly went to sleep. Thing is bc she waisted so much time hes sleep is off now. Hes in his boppy pillow at the moment everytime I put him in the pac and play he starts to fuss, diaper clean, fed. But bc hes been held most all day by her thats what he wants. Im mad. She even gives him a pacifier, hes only 5 days old I dont want him being one of the babies that HAS to have one and i dont want to use it as a mute button. I just feel like im being undermined. And its only day five. Top it off first thing she did when she came was vacuumed after my husband just vacuumed before they arrived. I just dont knw how to handle her.
