Bringing my 3 month old to a dance recital?

So basically, it is my nieces dance recital, who I love dearly, and has had to adjust to a lot of things this past year.

We used to be super close, but then I ended up getting a pretty demanding full time job, and I got pregnant. So I wasn't able to be over at her house every other day like I was with my part time job. I also live an hour away from her.

I was going to leave my 3 month old daughter with my mom for the day so that she could babysit ( this niece is my husbands niece not my biological one)

so that my niece could still have something that is special and completely hers. We also take her out to dinner at any restaurant she chooses after her recital.

Basically, leaving my daughter would mean my full on attention to my niece, I wouldn't have to worry about my daughter crying, or her ears getting hurt by the very loud music, and I wouldn't have to run off with my daughter when she needs to be fed.

The other thing Is I know my mother in law will feel like my daughter not being there is a personal attack, she complains about not seeing her, but we are always expected to make the hour drive to see them, and they never stop by to see us when they are in town, even when they are 15 minutes from our home. I am fully prepared to deal with the fall out from that.

But does anyone think I am making the right decision?

Or is it the wrong one?

Thank you for your helps, sorry that it's long!

Cheers :)
