I hate when other people hold my babies!

Hi- I recently had twins at the end of September. It has been really hard with bouts of postpartum depression and getting used to the new lifestyle. Even though things have been hard, I get really defensive when people want to hold my babies. ESPECIALLY my mother in law. It drives me absolutely crazy and I just want to yank my babies out of her arms, push her away and scream ‘THEY’RE MY BABIES!’... Is this normal? I’m trying to relax and get used to the fact that they are her grandchildren and she has a right to hold them but it really bothers me for some reason. My mom has been staying with my husband and I for the last 6 weeks and she has been amazing. I completely trust her and couldn’t do it without her. For some reason it’s just my MIL. We’ve had our issues in the past which could have something to do with it and she’s just an overbearing, obnoxious mother in law as it is but this is really getting to me. Anyone else feel this way?
