My MIL has always been a big part of my family whether I liked it or not. She's a good person, if anything, it's a major flaw. My daughter loves her grandma and, don't get me wrong, I love the relationship, but.....

We're on the worse side of broke. We've asked her for money who knows how many times, I don't even know how much we owe her. For context, her parents (my daughter's great grandparents) both passed away last year. Their deaths hit MIL pretty hard, especially because they were a few months apart (3 max), and her way of coping was shopping sprees. I didn't like it from the beginning because I knew that as soon as she got her head straight she'll start bitching about how much money she doesn't have because 
1) she has no monetary discipline
2) because of #1 her three sons (all adults) also have no monetary discipline
3) her parents had no monetary discipline
 So because of this, everyone is broke. 

This is all relevant in the fact that we were all hit pretty hard last year, so my husband and I promised that when we got our taxes we'd give her the majority. She got $6,000 out of roughly $10,000. A couple of days ago, maybe a week now, she hit a bump because some hardware store took money out of her account for a debt her father had left after passing. This was at the same time my husband was to pay her some bills (she's sort of our landlady). We were admittedly late by a couple hundred due work being a little slow, but we had plenty of time to give her the money before the bill was actually due. She bitched anyway because she was broke beo of her father's debt.

Today she had my daughter all day until tomorrow for a sleep over. I was already sketchy about it because everytime my  daughter goes over she gets some new toy that her father nor I could afford. Now, for the most part this is fine, but today she got a bike. Her very first bike. We were not consulted about this. We had planned to get her first bike for her birthday (she's turning three). On top of getting her her first bike, she immediately got to work on trying to teach her how to ride it. This was personal to me. I grew up without a dad so I was really REALLY looking forward to watching my daughter have that moment with her dad. Now she won't being her grandmother chose to do that.

Am I overreacting? I'm putting this up there with me telling my husband that I didn't like her kissing my babies on the lips when my daughter was first born. She still does this and husband plays it off as "this is what my family has always done." when I told him it bothered me that she was "having a difficult time kicking the habit"
