Am I asking for too much?

I've been married for almost 2 years now and we have 18 month old daughter. Before our daughter was born I expressed to my husband that I did not want my our children to be social media babies. I explained to my husband that I don't want my children to have pictures all over social media so much that they can Google themselves by the age of 5. I also let him know that if our children are posted on social media it should come from us. My husband agreed with my view.

I don't try to monitor him at any point. She's his daughter too and his first child I would never tell him not to express his joy over her. However, my problem has been with my mother in law. We have had our issues since I got pregnant. But we respectfully told her our choice not to have others including family members post pictures of our daughter on social media. She understood and agreed as well. But after my daughter turned 1 her respect for our rule went put the window. She posts almost every picture she gets and it irks my nerves. I am asking too much? I just want her to respect the choice my husband and I made for our daughter.
