I need to vent. MIL..

Okay starting rant now.

I love my MIL she is very kind and thoughtful and overall a very good person. However I find she favours grandkids. My SO has a 2yo ( let's call him Brad) from a previous relationship. My SO lived with his parents before we got together so for his sons first 5 months of life he was with both my SO and his grandparents. My MIL got obviously attached to my stepson. Fast forward, I had my first baby (let's call her Anna) and its my MILs first granddaughter (she has 3 grandsons). And I love my stepson to death of course I do but since my daughter is my first baby of course I'm going to spoil her with love and pictures and stuff right! So whenever I post pics of her my MIL always says you never post pictures of Brad he is there every weekend you know. And I know that but he hates getting his picture taken unless it's her taking it. And it's not like I don't ever post pictures of Brad. Just not as often! And there's another thing. She has tons of pictures and videos of Brad on her phone but maybe ONE of Anna! And I bought Anna a stuffed toy that lights up and plays music for babies and when my MIL saw it the first thing She said was "oh Brad would love something like that!" like can I not even buy my daughter something without her saying Brad needs one too? Even if it's a baby item? And another thing is whenever we visit her if we have both children she will pay all her attention to brad and only say a few words to Anna if brad is busy playing. She doesn't even acknowledge Anna until after we've been there for like 10 minutes! It really just bothers me. And the only time she will visit here is on the weekend when we have both kids. And one more thing, like I said about posting lots of pictures of anna, I put up a silly picture of Anna my SO and me on Facebook. My grandmother commented saying what a nice silly family photo and others as well. MIL commented And all she said was "where is Brad" because I posted the picture on the weekend when we have Brad. Mind you I took the picture a few days before. I know it's silly to let this bother me but it just does!

I know she loves Anna and all but it just gets to me how she pays her so little attention and how she always has to bring up brad whenever I mention Anna.

Ugh rant over. Tell me some of your crazy and annoying in law stories!!
