mother in law

This is all probably me being over dramatic or the fact that I just had a baby and my hormones are crazy but my mother in law is getting on my nerves. it is the little things she says like " our baby" or " I will feed him in less you think you can get him to eat more then I can." Also she gets in the same room as him and does not let him go, she has to be the one holding him. Any opinions, helpful tips, anything would be great. I don't know if I should say anything to my husband or not he will most likely say I am over reacting. HELP!
