What would you have done?

This event happened this past Christmas when my husband and I visited my In-Laws in CO, we live in MN. Up until this point I had an amazing relationship with my In-Laws but since Christmas I have had no contact with them. My husband and I make it a point to visit my In-Laws a few times a year as my FIL is very sick, and it's harder for them to come to see us then it is for us to see them. At least, it was. Over the holidays my MIL wanted to take my daughter (2 years old) Christmas shopping as we had previously planed on getting all of our Christmas gifts while out in CO rather than bringing extra bags to carry everything. There had been some light discussion on what everyone would purchase but the agreement was we'd all go together when my husband and I were out there to actually purchase everything. A well know rule I have, and have had since before my daughter was born was absolutely no CoCoMelon ever. I used to work in a daycare and have no interest in ever exposing my daughter to the show or branded merchandise. I need to be clear that I am fully aware I can't, and frankly have no intention on controlling what retail stores have in stock and choose to sell, I just don't want it purchased and given to my child. While shopping at Barnes & Noble (my MIL used to work there before my FIL got really sick and has coworkers who let her use their discount) my MIL gave my daughter a CoCoMelon branded train. I asked her to not give it to my daughter as I don't want her to have CoCoMelon toys. My daughter absolutely loves trains and I didn't want her to get any attachment to a toy she couldn't have. My MIL instantly got quite and took everything we had gathered to checkout. The plan afterwards was to go out to lunch but my MIL and SIL canceled and told us they were suddenly not feeling well and were going back to the house. My husband and I also decided to skip lunch and went back to the house as well. Shortly after we got back, my MIL and SIL sat us down at the table and my MIL called my actions "tyrannical", yes that's the exact word she used, and told me (and my husband, but it was directed at me) that we really need to reconsider if this was the "hill we'd die on" as they would have to reconsider they're involvement in our daughter's life if it was. I will take the time to elaborate on the dynamic we'd devolved while on these visits to my In-Laws. As mentioned before, we try to go out to visit a few times a year. My husband had a generous PTO allowance so we typically visit for upwards of 2 weeks at a time, this past trip planned was for 3 weeks. I understand that they don't get to see my daughter very often, so I try to let them have as much time as possible while there. Before this trip I had always made it a point to be in the same room as my daughter as I don't expect them to be her primary caregiver while we visit. They have told me more times than I can count that they are more than fine with caring for her, and actively push me away so I can relax and let them care for my daughter. This past trip is the only time I have ever taken them up on that offer, every other trip I have made sure to make a point of being easily and readily available for any reason. After my MIL called my action tyrannical I fully admit I shut down. I did my best to excuse myself as quickly as I could so my husband and I could talk about it away from them. That night the decision was made that we would stay for Christmas and leave on the 27th. The next morning, the 24th, my MIL spoke to my husband without me and from what was told to me by him, doubled down and reiterated that if I was truly going to die on this hill they wouldn't want to be around our daughter alone ever again "for fear of upsetting" me. At this point, I no longer feel comfortable staying with them and have no desire to spend the holidays with them anymore. I had another long and difficult conversation with my husband and we both agreed that I'd leave with our daughter that night to go back home. We also both agreed that he'd stay until the 27th, to try to see if things could be worked out with my In-Laws. My marriage hasn't been in a great place since and I've had no contact with any of them since. Yesterday my SIL called my husband and the summarized version he told me was my In-Laws don't know how many years it'll be before they're able to forgive me for taking my daughter when and how I did. They also told him they are so traumatized by what I did that they need to be in therapy now. I told him at this point, I'm no longer comfortable with them having any involvement in our daughter's life and frankly, I don't want him speaking to them either. My only regret is the pain this situation is causing my husband. I have no issue with my FIL and SIL, they are innocent in this. But I refuse to have any contact with his family until his mother apologizes to me and I stand by that. My only question is; what would you have done? Would you have left like I did or try to spend the holidays with them and work through this? Thank you for reading.
