Is it ok that I gave abandoned newborn kitten to a breastfeeding queen?

I have a stray cat that has a 2 week old litter of kittens. My friend found an abandoned 2 day old kitten in her backyard, the mom didn’t come back for it so I told her to bring it over and we gave it to the stray.

She didn’t reject the newborn but she didn’t embrace it either. It was crying making it’s way to her and now it’s breastfeeding. But she’s not making any effort in claiming the kitten. I just thought this would be the best option because if it was left alone it would die for sure.

Was it a bad idea? I’m scared I’ll wake up tomorrow to find the newborn dead bc of neglect :(
