They are both nursing at the moment. Mama is busy cleaning herself and I don't think she has any more but I'm going to hang out with her for a little while to make sure. Both placentas were delivered as well.
It's good they are nursing. It's also wise to hang out with her for a spell. Sounds like she's done well! She's such a beautiful cat. Can you tell what the babies look like yet? And have you placed her food, water, and litter nearby for her convenience?
Is the white kitten nursing well? It looks like fur is missing from its lower front legs, which is usually a sign of prematurity. If it's latching and nursing well it should be okay though.
Keep an eye on this kitten. It's important whether it's latching and nursing well. If not, you may want to supplement until it's stronger. Did you buy any kitten formula?
That's a good idea. The pre-mixed seems to cause digestive issues in kittens, so I only recommend the powder. Stay away from Hartz and Sergeant's brands. PetAg, GNC, and Royal Canin are all good. A dish a day is good for mom too while she's lactating.
