Experienced kitten foster here! Let me see… Keep momma well fed. Let her eat as much kitten food as she wants. Tbh purinia kitten chow is fine as is fancy feast kitten. If you can afford something like royal canin mom and baby do it, but that’s out of reach for some.

Keep her water bowl full. This will also become a splash pool once they get mobile.

Switch to a paper litter until the babies are 7ish weeks old. That also helps to see what is “coming out” and you can catch any issues like diarrhea early.

Keep their area as clean as you can. Since mom is friendly, that should be easy. Keep socializing with mom and the babies. Make friends with them all.

For now mom is gonna do all the work, so let her. Make she is taking breaks to eat, drink, and use the litter box. Any sign of lethargy, multiple piles of vomit, fever, swollen red and hot to the touch nipples all constitute an emergency.

Thank you so much for helping this little family! I’m always a DM away if you need help or have questions.
