MIL baby shower issues

Am I in the wrong?

I honestly wanted to have the baby shower end of May but she wanted to hold out.

Since the COVID situation hasn't really changed she talked about doing a drive-by shower where they drop off a gift and get out of the car and say hi, I open the gift then and there and we give them a cupcake. (Uh to me that is a open house, not a parade)

She is having foot surgery on Monday. She is supposed to keep her foot above her heart until the 22nd.

I went ahead and planned a parade with actual social distancing for the 20th and invited people.

She is mad because she wanted to be apart of it and is now going to have to hear it while she's stuck in bed.

I don't want to push it out a week because my dad is trying to be an actual dad and already planned a get-together that day. He planned this before. My husband is trying to tell me to try to get my dad to reschedule so we can have it that day but I don't think that is right of me to ask of my dad especially when they are trying to have a real relationship and they've already invited my other siblings.

She already guilt-tripped my bro in law to cancel his barbecue that was going to be today where we meet his fiancees family because she can't go even if we are distanced apart/wearing masks when not eating because she has to self-quarantine for the surgery and she really wants to meet them.

The weekend after my dad's thing is July 4th so that's a no.

I really don't want to push it out further in July because the baby could come at any time (granted I realize baby could come now if he wanted to do so) and I'm already stressing making sure we will at least have the essentials as it is and be able to let them sit for a while even after disinfecting them.

Update:

When I had asked her about end of May she was hoping that someone else was going to throw one.

She was there and her daughter created the FB event when I decided on the 20th. She didn't throw a stink for a couple of days later. The event I planned and the one she planned are two separate ideas. My idea is an actual parade of cars no stopping keeping social distancing in place.

When we planned it she talked about how her mother in law and girls can help if she can't. When it was planned I told her of my cousins willing to help and even throw one she turned it down.

We pointed out that we can record/stream it and she could even watch out the window but that wasn't good enough because she wants to socialize with everyone when we've explained that I'm not comfortable with them stopping. We told her we can have it at a different location and she wants it there.

I was the one who has decorations beforehand that she liked and wanted to use. She wasn't going to pay for anything.

My dad's event was planned before she even talked about a shower. My dad invited me when he hasn't wanted to do anything with me for over 2 years. He wants our relationship back. His event was planned first has nothing to do with the baby. I don't think its fair for me to be all yeah you have to move your event so we can have a baby shower otherwise I can't go to your event.

We are already pushing out celebrating my husband's birthday for her until after the 22nd. Neither that or his brother's bbq has a new date.

She held off the surgery when she could have had it last month.
