Just want to be able to do what I want to do

Without feeling guilty of taking someone’s time away from them to watch the baby. Like just take a nice long shower, or take my time getting ready, or even taking a nap. Husbands playing a video game and I just ask him to watch the baby while she naps so I can get ready so we can go downtown. His response is ‘she’s fine you gotta be able to do this when I’m not here’ butttt you are here so can you just get her if she wakes up/cries?? Like I would like to be able to not have anxiety about rushing to get ready so you can get back to doing what you want to do.
