Pooping during naps??

So my daughter used to have good 1-2 hour naps 2-3 times per day. For the last week, WITHOUT FAIL, she poops during every single nap she has after 15-20 mins of sleeping then she’s up. Will not go back down until her next nap time (2.5-3 hours later). Sometimes she’s fine with these catnaps, sometimes she grumpy. But I need more than 13 minutes to myself during the day as when she’s up she’s a very busy girl, needs to be interacted with. I have stuff to do!! Any help would be appreciated, but I’m partially just ranting and seeing if anyone has the same issue.

She’s breastfed and has been started on purées.
