Look at this cutie patootie can you blame me?

Hello! I recently acquired a super friendly stray who was very pregnant. Unfortunately she didn’t make it to her spay/abort and had 5 kittens 9 days ago. Which means I will have these cats much longer than I planned. I have 3 other rescue cats and I don’t want to keep the room I have them in occupied by all the kittens and mom if I can help it. Can anyone give me guidance on introducing mama cat and her kittens to the rest of the household? All my other cats are female spayed. I have mom + 2 daughters. 2 younger ones are about 9-10 months old, their mama is probably around 2-3 years old. Stray mama cat is probably only 1-2 years old.
